Jun 12 21:46:24 <grothoff> Hi!  On my plug (running stock ubuntu with kernel 2.6.22.18) the pdflush kernel process often takes 99% CPU for extended periods of time, making processes doing IO irresponsive for
Jun 12 21:47:18 <grothoff> many minutes.  I looked at dirty pages, and there were only a handful.  This even happens if there is no major IO going on at all in the first place.  Any suggestions?  Anyone else experiencing this problem?
Jun 12 21:49:52 <grothoff> (I should mention that I am using a 4 GB USB stick for /home, but the problem does not seem to be limited to writes to /home).

Jun 12 22:11:17 <Bryanstein> sonic74,
Jun 12 22:12:18 <Bryanstein> oh pfff he's been idle for 6 hours...sleeping
Jun 12 22:25:03 <dattaway> grothoff: I had that happen too... it was my my slow SD card with the writes being too slow... turning cron off helped, but I eventually moved root over to a real hard drive
Jun 12 22:26:50 <dattaway> so much faster
Jun 13 00:41:00 <sonic74> Bryanstein?
Jun 13 00:42:43 <scientes> yeah ive tried with 4 differnt kernels now, and still cant get my usb serial to work
Jun 13 00:42:45 <scientes> this sucks
Jun 13 00:45:12 <Bryanstein> yes sonic74
Jun 13 00:45:19 <sonic74> aah
Jun 13 00:45:46 <Bryanstein> the ole u70
Jun 13 00:46:09 <sonic74> hmm, then-p 0103
Jun 13 00:46:16 <sonic74> should be correct.
Jun 13 00:46:16 <Bryanstein> I did that
Jun 13 00:46:20 <Bryanstein> that is what I have sonic74
Jun 13 00:46:30 <Bryanstein> I found that in a few places actually
Jun 13 00:46:36 <sonic74> hmm, I'll try myself again...
Jun 13 00:47:36 <sonic74> I ran it just now sucessfully with
Jun 13 00:47:37 <sonic74> LD_LIBRARY_PATH=/usr/local/lib/ /usr/local/bin/slugterm -k /dev/input/event0 -p 0103 -i 00203c7ac9f26c48f97053ffff2127032091f3fffffff901e00102c819 -f /tmp/10x20.bdf -c /bin/bash &
Jun 13 00:47:57 <sonic74> !handle
Jun 13 00:48:10 <sonic74> is printed when the USB device can't be opened.
Jun 13 00:49:28 <Bryanstein> well I'm not sure why it couldn't be opened
Jun 13 00:49:40 <Bryanstein> the displaylink crap can open it
Jun 13 00:50:16 <Bryanstein> sonic74, tell me this
Jun 13 00:50:19 <sonic74> can you give me the output of
Jun 13 00:50:22 <sonic74> lsusb
Jun 13 00:50:22 <sonic74> ?
Jun 13 00:51:46 <Bryanstein> 1 sec
Jun 13 00:52:25 <Bryanstein> http://pastebin.ca/1458429
Jun 13 00:52:54 <dyjdrtrtjd> its not plugged in
Jun 13 00:53:25 <Bryanstein> dyjdrtrtjd, talking to me?
Jun 13 00:53:34 <Bryanstein> well the tests work when I run them
Jun 13 00:53:41 <Bryanstein> the display link ones that is
Jun 13 00:53:49 <dyjdrtrtjd> oh thats from the plug
Jun 13 00:53:50 <Bryanstein> not as they should...but they work
Jun 13 00:53:50 <sonic74> strange.
Jun 13 00:54:15 * Bryanstein looking for another hub
Jun 13 00:55:41 <Bryanstein> sonic74, you tried running the u70 without a hub yet?
Jun 13 00:55:48 <sonic74> no.
Jun 13 00:55:59 <sonic74> power isn't sufficient.
Jun 13 00:56:18 <sonic74> U70 needs 1 A, SheevaPlug delivers 0.7 A.
Jun 13 00:56:41 <sonic74> my hub:
Jun 13 00:56:49 <sonic74> Bus 001 Device 002: ID 0409:005a NEC Corp. HighSpeed Hub
Jun 13 00:57:01 <sonic74> powered USB 2.0
Jun 13 00:58:43 <Bryanstein> well I have a usb 1.1 hub previously...it still acted funny...but I didn't try slugterm then
Jun 13 00:58:58 <Bryanstein> sonic74, can you get displaylinks driver to show the demo correctly?
Jun 13 00:59:04 <Bryanstein> it's a very simple install
Jun 13 00:59:08 <sonic74> I never tried.
Jun 13 00:59:09 <sonic74> how?
Jun 13 00:59:11 <Bryanstein> but the images don't show
Jun 13 00:59:17 <Bryanstein> wait I'll link you
Jun 13 01:00:04 <Bryanstein> http://people.freedesktop.org/~berniet/libdlo-0.1.0.tar.gz
Jun 13 01:00:09 <Bryanstein> lol that is all to it
Jun 13 01:00:19 <Bryanstein> apt-get install libusb-dev
Jun 13 01:00:37 <Bryanstein> then ./configure; make install; make check
Jun 13 01:01:31 <Bryanstein> well && instead of ; ...incase it fails...you know
Jun 13 01:01:38 <Bryanstein> http://freedesktop.org/wiki/Software/libdlo
Jun 13 01:03:29 <Bryanstein> sonic74,  also
Jun 13 01:03:44 <Bryanstein> edit that test1.c change it to 800 x 480
Jun 13 01:03:53 <Bryanstein> then run make check again
Jun 13 01:04:49 <Bryanstein> it tries some ridiculous resolution by default the screen can't handle...you also have to run that as root from the test dir
Jun 13 01:05:03 <Bryanstein> if not it won't work and the program won't see the images
Jun 13 01:06:31 <sonic74> I see a white screen and then some... bars.
Jun 13 01:06:39 <Bryanstein> see what I mean LOL
Jun 13 01:06:48 <Bryanstein> but...that initializes like a champ
Jun 13 01:06:54 <sonic74> perhaps it's supposed to look this way?
Jun 13 01:07:01 <Bryanstein> NO
Jun 13 01:07:12 <Bryanstein> sonic74, if you open the images dir with gqview or something
Jun 13 01:07:18 <Bryanstein> you'll see how good it should look
Jun 13 01:08:14 <sonic74> ah, a logo.
Jun 13 01:08:33 <sonic74> I started SlugTerm again aftermake check
Jun 13 01:08:42 <sonic74> and it works. hmm.
Jun 13 01:09:38 <Bryanstein> man this sucks for me LOL
Jun 13 01:09:49 <Bryanstein> you built on the plug?
Jun 13 01:09:54 <sonic74> yes.
Jun 13 01:10:18 <sonic74> (for the plug. for OpenWRT, i built it on my linuxbox)
Jun 13 01:10:39 <Bryanstein> oh well wtf
Jun 13 01:10:45 <Bryanstein> I'm missing something
Jun 13 01:11:05 <Bryanstein> I don't think its power...I even tried stealing power from another machine
Jun 13 01:11:20 <sonic74> if libdlo works...
Jun 13 01:11:25 <Bryanstein> that one cable that doesn't have the usb logo on it is just for power
Jun 13 01:11:28 <Bryanstein> well yes it does
Jun 13 01:13:24 <Bryanstein> sonic74, it works like you saw it work...hardly...it initializes then beyond that the images suck
Jun 13 01:13:51 <Bryanstein> sonic74, you saw the few libs I had to install to get it running...you think I'm missing anything?
Jun 13 01:13:51 <sonic74> have you tried the kernel framebuffer driver?
Jun 13 01:14:10 <sonic74> I don't think so, since that would bring error messages.
Jun 13 01:14:18 <sonic74> I'm implementing error handling...
Jun 13 01:27:30 <sonic74> what happens with
Jun 13 01:27:30 <sonic74> http://sven.killig.de/openwrt/slugterm
Jun 13 01:27:34 <sonic74> ?
Jun 13 01:28:00 <sonic74> Bryanstein
Jun 13 01:28:19 <Bryanstein> sonic74, when I run it?
Jun 13 01:28:27 <sonic74> yes
Jun 13 01:28:33 <Bryanstein> oh the openwrt one
Jun 13 01:28:35 <Bryanstein> never tried it
Jun 13 01:28:42 <sonic74> no, the new binary
Jun 13 01:28:46 <sonic74> http://sven.killig.de/openwrt/slugterm
Jun 13 01:29:17 <Bryanstein> the last one....no segfault at the start...it runs...farts out some messages...then segfault
Jun 13 01:29:28 <sonic74> I meant this one:
Jun 13 01:29:28 <sonic74> http://sven.killig.de/openwrt/slugterm
Jun 13 01:29:37 <sonic74> (it's the binary only)
Jun 13 01:29:46 <Bryanstein> yes that is what I've been playing with
Jun 13 01:29:58 <Bryanstein> I thought that first link was something else...because there are 2 bins
Jun 13 01:29:58 <sonic74> but I compiled it just some seconds ago?
Jun 13 01:30:16 <Bryanstein> oh...I thought you meant the one previously, since you last emailed me
Jun 13 01:30:19 <Bryanstein> 1 sec
Jun 13 01:33:36 <Bryanstein> !usb_get_device_handle(0x17e9, 0x0103)
Jun 13 01:33:54 <sonic74> correct IDs. damn.
Jun 13 01:34:38 <sonic74> the code:
Jun 13 01:34:42 <sonic74> handle = usb_get_device_handle( 0x17E9, pid );      if (!handle) {           printf("!usb_get_device_handle(0x17e9, 0x%04x)\n\n", pid);           return false;      }
Jun 13 01:34:51 <sonic74> can't imagine what can go wrong there.
Jun 13 01:35:12 <sonic74> (apart from other processes holding a lock)
Jun 13 01:35:23 <sonic74> (which happens if I start it twice)
Jun 13 01:35:35 <Bryanstein> sonic74, I am now trying this with one cable in the plug and one stealing power from another pc
Jun 13 01:36:26 <Bryanstein> I just gave away my good hub...let me walk around and see if anyone has a hub
Jun 13 01:39:31 <sonic74> perhaps a
Jun 13 01:39:31 <sonic74> lsof|grep usb
Jun 13 01:40:15 <sonic74> Bryanstein
Jun 13 01:40:27 <Bryanstein> yep
Jun 13 01:41:18 <Bryanstein> well nothing has it open
Jun 13 01:41:37 <sonic74> are you root?
Jun 13 01:42:40 <Bryanstein> yep...sudo action...wait let me try your original init
Jun 13 01:42:51 <Bryanstein> I think mine is screwed up...even though it lets it run
Jun 13 01:43:52 <sonic74> -i happens after -p ...
Jun 13 01:45:21 <Bryanstein> ok wait
Jun 13 01:46:58 <Bryanstein> ah
Jun 13 01:47:16 <Bryanstein> she works...I see it...but no input to it
Jun 13 01:47:22 <sonic74> aah
Jun 13 01:47:31 <sonic74> have you installed my kernel?
Jun 13 01:47:39 <sonic74> (uImage)
Jun 13 01:48:26 <sonic74> without it, there are no
Jun 13 01:48:48 <sonic74> dev/input/event*
Jun 13 01:48:50 <sonic74> devices
Jun 13 01:49:17 <Bryanstein> I saw that
Jun 13 01:49:51 <Bryanstein> sonic74, what is your full name?
Jun 13 01:49:59 <sonic74> Sven Killig
Jun 13 01:50:28 * Bryanstein will make sure he prints out something with your name on it
Jun 13 01:50:33 <sonic74> :-)
Jun 13 01:50:35 <Bryanstein> I'll sit it right next to the plug
Jun 13 01:50:55 <sonic74> would love to be there. South Carolina...
Jun 13 01:50:58 <Bryanstein> ok wait...this is sooooooooo damn sexy
Jun 13 01:51:11 <sonic74> always wanted to visit the USA...
Jun 13 01:51:36 <Bryanstein> sonic74, if you ever come to the US ...come to Florida...I can give you free stay
Jun 13 01:51:44 <sonic74> :-)
Jun 13 01:51:49 <Bryanstein> and you can speak at a conference
Jun 13 01:52:19 <Bryanstein> we have one Oct 24...Florida Linux Show
Jun 13 01:52:45 <sonic74> @ university, too? I'm a student...
Jun 13 01:53:07 <Bryanstein> if you get here...I can set you up
Jun 13 01:53:31 <sonic74> Orlando...
Jun 13 01:54:17 <Bryanstein> Yes...I have a time share there in Orlando...about 15 minutes from Disney lol
Jun 13 01:55:02 <sonic74> what do you mean with "time share"?
Jun 13 01:55:08 <Bryanstein> and I live in Jax which is about 1hour and 30 minutes away...no matter what...you'd be taken care of...this would be very nice for you C.V.
Jun 13 01:56:01 <Bryanstein> sonic74, its where you pay for a condominium or vacation quarters
Jun 13 01:56:18 <Bryanstein> and others share it on and off...you rotate different times
Jun 13 01:56:49 <sonic74> ah, sort of a cheap long term hotel.
Jun 13 01:57:12 <Bryanstein> sonic74, oh no...far from cheap
Jun 13 01:57:22 <Bryanstein> you actually own this when you're done paying for it
Jun 13 01:57:33 <sonic74> oh, OK.
Jun 13 01:57:59 <Bryanstein> it's a resort
Jun 13 01:58:08 <sonic74> I see.
Jun 13 01:58:22 <Bryanstein> http://www.silverleafresorts.com/resorts
Jun 13 01:59:23 <Bryanstein> I have 2 ambassador suites 1 in Orlando and another is Missouri...my buddies at fli4l all welcomed me...when even I come to Deutschland
Jun 13 02:00:08 <Bryanstein> sonic74, you need some place else to host those files too?
Jun 13 02:00:50 <Bryanstein> a mirror..I know your little site gets a lot of traffic
Jun 13 02:02:14 <sonic74> looks nice!
Jun 13 02:02:15 <sonic74> when reddit, engadget and makezine hit me, my DSL line got a bit crowded, and I moved the JPGs and MP4s to the university server. but since then, traffic has decreased to a very manageable level.
Jun 13 02:02:48 <Bryanstein> lol you don't have any numbers? how much traffic did you get?
