**** BEGIN LOGGING AT Sun Apr 11 02:59:56 2010 Apr 11 17:51:55 Are you familiar with bugs like this on omap: [ 2361.163635] BUG: soft lockup - CPU#0 stuck for 61s! [dpkg:1737] Apr 11 18:03:28 nosse1: I've seen that error reported for all sorts of architectures. Unfortunately, I don't know the cause. I'm fairly certain it's not OMAP-specific though. Apr 11 18:04:28 persia, thanks. I'd just wanted to check if it was something familiar on omap. Apr 11 18:04:39 what's the error? Apr 11 18:04:47 sorry, just popped in, so I don't have the backscroll Apr 11 18:05:02 [ 2361.163635] BUG: soft lockup - CPU#0 stuck for 61s! [dpkg:1737] Apr 11 18:05:04 nosse1: which kernel are you urins? Apr 11 18:05:04 BUG: soft lockup - CPU#0 stuck for 61s! Apr 11 18:05:09 *using Apr 11 18:05:16 nosse1: the TI one? Apr 11 18:05:49 I'm running the TI-one yes, the "official" lucid ti-omap won't work for AM3517 Apr 11 18:06:33 It could seem to me that the lockup occurs on heavy disk activity. And since I'm running NFS root, it could perhaps be related to that? Apr 11 18:09:20 could be, but hard to say without more information from the kernel Apr 11 18:09:57 Yeah, I know. Except the kernel doesn't tell any more Apr 11 18:10:15 Another thing: I have X up and running (yeah!). Apr 11 18:10:40 Martyn: did i ask you if you had sound running on the tegra? Apr 11 18:11:02 What apt target do you guys use when testing? "ubuntu-netbook" has unknown packages which doesn't seem to be available yet Apr 11 18:11:46 Do you have a all-in-one target which pulls down the gnome desktop? Apr 11 18:12:17 That'd be ubuntu-desktop, but ubuntu-netbook is significantly lighter-weight in terms of requirements. Apr 11 18:12:44 Which bits of ubuntu-netbook aren't installing? Apr 11 18:12:51 persia, hold on Apr 11 18:15:13 persia, cancel that. It seems all packages are available now Apr 11 18:16:12 There's sometimes architecture skew with the mix of arch:all and arch:any binaries (because the arch:all binaries are built on i386), but it doesn't typically last that long, unless something broke (which means it needs fixing). Apr 11 18:16:30 If you get a persistent issue with metapackage installation, it may well be a bug needing fixing. Apr 11 18:16:42 (but I'm glad to hear this isn't the case right now) Apr 11 18:17:22 That said, according to https://launchpad.net/builders there are 19 packages that are out-of-date on armel (waiting to build). Apr 11 18:19:16 Are there any commercial developers here in this forum? (perhaps not on sundays) Apr 11 18:19:41 I'm uncertain if we should register our products on the ARM machine registry or not Apr 11 18:20:49 and I'd like to know what other mfgs are doing Apr 11 18:21:10 armin76 : Since I'm very server-oriented, I haven't even tried to get sound working on the tegra Apr 11 18:21:21 armin76 : I've even disabled video, to get the memory back Apr 11 18:21:54 nosse1: Do you need a special MachineID for your hardware? If so, you'll want one. If not, there's little point. Apr 11 18:22:07 nosse1 : I'm a 'comercial developer' Apr 11 18:22:13 Martyn: nod :) Apr 11 18:23:25 persia, I'm not sure i need one. You use machineid whenever the kernel isn't aware of the HW its running on, right? If that is true, I guess we don't need one Apr 11 18:24:07 I don't really understand when it's needed, but I think it's part of kernel compilation: if you can run a multi-board kernel, I think you don't need it. Apr 11 18:40:55 Alas, it seems NFS root is the culprit of the kernel crashes Apr 11 18:41:26 * nosse1 wish that the AM3517 had a SATA disk connector... Apr 11 18:49:32 Anything designed to have disks should have such a controller, but MTD rules when it comes to local data. Apr 11 19:16:34 persia, do you mainly use USB or SD MTDs? Apr 11 19:16:58 I've never used an MTD that wasn't on-board. Apr 11 19:17:15 I'm fairly certain that neither USB nor SD allows one to actually use the MTD drivers. Apr 11 19:29:17 persia, you need a fairly large mtd if you want to do development on it. E.g. for building packages (since Ubuntu builds natively). Do you know how it's done in the build farm? Apr 11 19:29:44 morning Apr 11 19:30:16 (I'm somewhat bothered here having to reboot my target whenever I do a larger apt install) Apr 11 19:31:13 nosse1: I'll say that an MTD is inappropriate for doing development: for that you want spinning disks. Apr 11 19:31:30 yes Apr 11 19:31:37 I believe the build farm uses SATA-over-USB but I may be mistaken. Apr 11 19:31:41 connecting 1.5TB disk over usb is easy Apr 11 19:31:52 That's probably overkill :) Apr 11 19:31:58 Ah. Apr 11 19:32:04 persia: I have such one connected to sheevaplug Apr 11 19:32:35 I'd rather use an esata-bearing sheeva. =รพ Apr 11 19:32:40 or rather had as I have some problems with sheeva so disk is connected to desktop Apr 11 19:32:45 Because we need to make one ourselves unless we somehow can build packages natively on our large build farm Apr 11 19:32:55 DanaG: I bought sheevaplug year ago when it was new stuff Apr 11 19:33:21 nosse1: connect sata-over-usb and pray that TI ehci will work Apr 11 19:34:12 So it's about praying for one or the other. One=NFS, Other=ehci.... NFS crashed once more *sigh* Apr 11 19:34:31 ehci is probably more stable than NFS in most ways. Apr 11 19:34:37 nosse1: 16GB sd is other option Apr 11 19:34:47 I remember that NFS was discussed for the LP build farm and rejected, but I don't remember why. Apr 11 19:35:04 hrw: If you like buying new SD cards :) (but 4-8G is enough for most packages) Apr 11 19:35:05 nosse1: quite cheap, easy to buy and omap3 can drive 3 mmc/sd slots Apr 11 19:35:49 I have here device with omap3 and 3 sd slots. mmc0=rootfs, mmc1=userfs, mmc2=sdio/wifi/bt Apr 11 19:35:52 How's wear levelling handled on SD? Is it the SD firmware, or is it up to the host SW? Apr 11 19:36:02 SD itself Apr 11 19:36:49 ...and from what I've heard it spans from excellent to horrible Apr 11 19:37:08 yes Apr 11 19:37:31 Reliable brands: SanDisk, Kingston ? Apr 11 19:38:00 * nosse1 needs to shop SD cards tomorrow Apr 11 19:38:06 sandisk Apr 11 19:38:12 avoid kingston rather Apr 11 19:39:57 hmm, where can you get a cheap sdio wifi? Apr 11 19:40:07 I wanna' try one in my host computer's sdhc controller. Apr 11 19:40:13 DanaG: no idea Apr 11 19:40:27 DanaG: here I have marvel8686 in two devices - both on sdio Apr 11 19:40:39 and 3rd one has it on spi bus Apr 11 19:40:57 Something weird with the Ricoh reader in Windows: it assumes the whole disk is one partition (even if it's not true)... and then can't comprehend what partition type. Apr 11 19:41:21 common Apr 11 19:41:34 I end up having to use "rw-everything" (awesome tool, by the way) to essentially "setpci" as I would have to on Linux... and then it reattaches to the SDHC controller instead of the Ricoh controller. Apr 11 19:41:39 brand new cards sometimes do not have partition table Apr 11 19:41:47 http://intr.overt.org/blog/?p=59 Apr 11 19:42:04 The card I was testing with, was my beagle (two partitions). Apr 11 19:43:36 Once I did that, it then showed partitions properly. Apr 11 19:43:44 I'm curious to try some SDIO card with the thing. Apr 11 19:43:56 DanaG: nice Apr 11 19:45:16 I did the writing value on the mmc controller function, specifically. Apr 11 19:56:46 but - is each sd controller also sdio capable? Apr 11 19:59:26 hrw, After skimming the RM from TI, it seems so Apr 11 20:00:21 nosse1: I know that i.mx31, omap3, pxa2xx are sdio capable. no idea about others **** ENDING LOGGING AT Mon Apr 12 02:59:56 2010
