**** BEGIN LOGGING AT Thu Dec 15 02:59:57 2011 Dec 15 05:28:22 16:20 mikef: battery stats per hour, gave it power just after penultimate entry http://paste.debian.net/149276/ Dec 15 05:29:24 So the TF101 (running Ubuntu) has a discharge rate of 12% to 14% per hour (of the onboard battery). That works out to be about 7.14 hours of life. The dock is half as much battery again, so that comes to about 10.7 hours of life with my current config. Dec 15 05:29:44 *without* sleeping or screen blanking on inactivity Dec 15 05:31:00 brightness is at 157/255 (default at boot time) Dec 15 05:38:32 lilstevie: ^^ Dec 15 05:38:53 Anybody riced up stuff to save power on the TF yet? powertop doesn't look to be very helpfu Dec 15 05:41:38 twb: my average consumption is 10% per hour Dec 15 05:41:47 The only thing it recommends that I can see is /proc/sys/vm/dirty_writeback_centisecs Dec 15 05:41:55 Which is 6000 and it thinks 1500 is better, but it isn't Dec 15 05:42:01 lilstevie: hum Dec 15 05:42:11 lilstevie: well, I am using an offboard keyboard, and wifi Dec 15 05:43:07 http://www.lesswatts.org/tips/disks.php et al Dec 15 05:43:14 I get 19hours 40 with no power management Dec 15 05:43:17 wifi on Dec 15 05:43:24 but using the dock keyboard Dec 15 05:43:31 Be interesting to know what else is different Dec 15 05:44:02 with LP0 suspend to ram though :p Dec 15 05:44:08 There is autosuspend for the keyboard power, but if you turn it on, the keyboard won't wake from sleep :-( Dec 15 05:44:09 you probably don't want to know Dec 15 05:45:06 also my wake is based off the dock "lid open switch" Dec 15 05:45:39 Surely the 19.6 hrs doesn't count the hours that it's suspended to ram Dec 15 05:45:47 In which case suspend to ramdoesn't matter Dec 15 05:46:25 19.6hours was without LP0 Dec 15 05:47:25 The dock battery is half the size of the tablet battery, right? Dec 15 05:47:39 no Dec 15 05:47:40 same size Dec 15 05:47:44 identical Dec 15 05:47:46 Oh, OK Dec 15 05:48:02 In that case I should get ~14 hours atm Dec 15 05:48:54 last 4.4h used 1% battery Dec 15 05:48:56 :) Dec 15 05:50:31 only issue with LP0 I can see at the moment is the battery does not charge from the dock while in that mode Dec 15 05:50:43 so you think it's like a car, where the "empty" mark is WAY above the actual empty level? Dec 15 05:51:08 the dock does not drain past 3% Dec 15 05:51:18 Well yeah, not counting that Dec 15 05:51:38 and not "way above" Dec 15 05:51:43 but still a little bit above Dec 15 05:52:26 just not all batterys are created equal Dec 15 05:53:51 batteries even Dec 15 06:01:58 Is irqbalance useful on tf? Dec 15 06:02:35 Also for some reason my load average never drops below 1 Dec 15 06:06:09 Greetings ubuntu-arm, is it a known bug that the current build has EXT4 journal corruption bugs? Dec 15 06:06:28 cmcmanis: current build on what platform? Dec 15 06:06:40 sorry pandaboard Dec 15 06:06:51 Got a new Pandaboard-ES and put the current Ubuntu on it Dec 15 06:07:23 It corrupts the EXt4 journal and then I have to reboot. I can reproduce by just dding from /dev/zero to a file Dec 15 06:09:56 cmcmanis: Define "current Ubuntu". Dec 15 06:10:12 cmcmanis: But I have no such issues on my Panda. Is this running on an SD card? Dec 15 06:10:20 cmcmanis: (If so, I'd suspect your SD is dying) Dec 15 06:10:22 sorry, the build that is referenced off the pandaboard.org site one sec Dec 15 06:11:25 ubuntu-11.10-preinstalled-server-armel+omap4.img.gz Dec 15 06:11:38 SD is brand new, kingston class 10 Dec 15 06:11:47 New doesn't mean much. :/ Dec 15 06:12:09 I can tell you for sure that a fresh install of oneiric shows no such weirdness on any Pandas here. Dec 15 06:12:11 fair enough Dec 15 06:13:05 I actually only have on card I've never managed to kill. And I suspect that's more luck than anything else. Dec 15 06:13:15 SD and random access don't really get along. Dec 15 06:13:25 true that Dec 15 06:13:41 (If you have a USB HDD for your Panda, I'd recomend grabbing a netboot image, stuffing that on an SD, and installing to a hard drive) Dec 15 06:14:21 Hmmm that is an interesting idea. Dec 15 06:21:37 17:02 It corrupts the EXt4 journal and then I have to reboot. I can reproduce by just dding from /dev/zero to a file Dec 15 06:21:47 That sounds to me more like the filesystem is bigger than the disk or something Dec 15 06:22:02 Or the blocks where teh journal lives aer toast Dec 15 06:22:23 twb: it would be the latter rather than the former Dec 15 06:22:42 cause unless the SD card is <2GB that wouldn't happen Dec 15 06:23:00 aye, that would cause it but I've checked the partition multiple times, and can read and write both the first and last blocks (tested using dd) Dec 15 06:23:08 I just prefer to blame users, not hw :P Dec 15 06:23:08 Its and 8g card btw Dec 15 06:23:36 It came in a twin pack and I'm putting Android ICS on the other one we'll see if it has a similar issue Dec 15 09:27:51 * ogra_ scratches head about the eglibc build Dec 15 09:30:46 i wonder why the same package is built on two different builders Dec 15 09:42:01 ogra_: becasue you keep hammering those poor builders and they are revolting againt you now! :) Dec 15 09:42:10 haha Dec 15 09:42:15 ogra_: stop harassing the builders! Dec 15 09:42:19 the hammering seems to have stopped last night Dec 15 09:42:28 queue is largely empty Dec 15 09:48:37 ogra_: btw, did you sort out the ac100 "non booting kernel" problem? i read it could be toolchain related Dec 15 10:23:15 ppisati, well, in the package we have there are some issues with devices having hynix RAM, the micron ones seem to work fine ... with the new checkout that was rolled with gcc 4.6.2 it seems everything is broken Dec 15 10:31:06 ogra_: crap Dec 15 10:31:14 yeah Dec 15 13:22:09 hmm, lubuntu-desktop isnt installable yet on armhf Dec 15 15:02:00 ************* REMINDER ARM meeting in #ubuntu-meeting in 5min ****************** Dec 15 15:02:40 But I don't wanna go to school today mom. Dec 15 15:03:00 heh Dec 15 15:03:19 * ogra_ swings the cane Dec 15 15:03:33 :) Dec 15 15:04:59 infinity, could you run a check for universe packages not present on armhf, but present on armel? Dec 15 15:05:58 suit-diff should work... Dec 15 15:06:02 suite, too. Dec 15 15:06:05 But meeting time. Dec 15 15:08:37 doko: http://lucifer.0c3.net/~adconrad/universe-armel-armhf_differences Dec 15 21:12:24 my oneiric sys has now hung twice, even after scheduler Dec 16 01:37:09 lilstevie: I'm still losing 12%/hr, it really ought not to be the kb doing that :-/ Dec 16 02:37:34 twb: 2% difference really isn't that much Dec 16 02:37:40 and probably is the keyboard difference Dec 16 02:38:03 OK Dec 16 02:38:14 Just sayin, stinks that a kb uses 2%/hr Dec 16 02:38:47 btw, earlier installs had a problem where halting (from ubuntu) didn't fully power off the tf, so it drained the battery after a week or so -- does the current prime image (as at a week ago) still have that problem? Dec 16 02:39:13 it is still the same image Dec 16 02:39:38 and that will always have that problem of if it doesn't shutdown properly that it will drain the battery Dec 16 02:40:08 but if you suspend rather than halt, you should get 14 days, but I haven't pushed an image with suspend fix yet Dec 16 02:42:38 k Dec 16 02:42:57 What I am doing atm is if I won't be using it for a while, I boot into android and then halt from there Dec 16 02:43:08 Hopefully that actually results in a proper hard off Dec 16 02:43:41 yes that will Dec 16 02:43:47 Yay **** ENDING LOGGING AT Fri Dec 16 02:59:56 2011
