[08:27]  * henrix is having probs with isp... again
[08:32] <hrw> hi people
[08:33] <hrw> I bought Toshiba harddrive with usb 3.0. Connected to desktop (running quantal) and got this in dmesg: http://paste.ubuntu.com/1158604/ - disk is unusable as it connects/disconnects all the time
[08:35] <hrw> http://paste.ubuntu.com/1158610/ is lsusb -vvv output
[08:36] <hrw> ideas?

[08:46] <cooloney> ppisati: nice trip for vacation. heh
[08:47] <xnox> hrw: I am all ears, since I am experiencing similar. But for me it might be lvm related.
[08:48]  * xnox is not kernel dev, just a lurker.
[08:48] <ppisati> cooloney: thank you :)
[08:48] <hrw> xnox: http://www.digipedia.pl/usenet/thread/19505/33113/ is what I want to check
[08:49] <hrw> xnox: disk will be mostly used with usb2.0 laptop but for future use I prefer usb3.0 ;)
[08:50] <xnox> hmmm... for me it just spins down and gets "ejected" and then all of my LVs and VGs are borked =/ giving i/o errors. not sure it's the same.
[08:52] <cooloney> ppisati: if you need me take care of some ARM stuff during your vacation, please let me know
[08:59] <ppisati> cooloney: feel free to chime in, the ti-omap4 lp bugs page is always looking for some love :)
[09:49] <cooloney> ogra_: hey, i'm looking at the bug https://bugs.launchpad.net/ubuntu/+source/linux-ti-omap4/+bug/746137
[09:49] <ubot2`> Ubuntu bug 746137 in jasper-initramfs "Page allocation failure on Pandaboard and Beagle XM" [Undecided,Fix released]
[09:49] <ogra_> cooloney, ah, cool, note that this isnt arm specific 
[09:50] <ogra_> seems to be an issue with many USB based wlan cards
[09:50] <cooloney> ogra_: you mentioned to use GFP_ATOMIC instead of GFP_KERNEL, is that any bug about that?
[09:50] <ogra_> cooloney, not sure, marvin24 pointed me in #ubuntu-arm to it 
[09:50] <ogra_> ask him, i guess
[09:51] <cooloney> ogra_: oh, can we reproduce on x86? actually i got this on my pandaES frequently
[09:51] <ogra_> i think you can if you boot with a really low mem= value and have the same highmem split in the kernel 
[09:52] <ogra_> but ask marvin24, he was really into that bug for a while
[09:52] <cooloney> ogra_: ok, cool
[09:55] <cooloney> ogra_: also from infinity's comments, looks like if we change vm.min_free_kbytes = 32768, the issue is gone
[09:55] <ogra_> right, its just that we dont want to set that var for everyone...
[09:55] <ogra_> and setting a sysctl variable conditionally isnt easy
[09:56] <ogra_> also its somnething that looks like the kernel should set it right
[09:56] <ogra_> instead of userspace with hackish detection scripts
[09:57] <hrw> II: Checking modules for generic...previous or current modules file missing!

[09:57] <hrw> argh...
[10:00] <hrw> how to disable all abi checks etc? I want to test some usb3.0 patches and kernel compilation drives me mad
[10:07] <cooloney> ogra_: looks like marvin24 is not online
[10:08] <ogra_> patient :) its noon here, he is probably at lunch
[10:08] <cooloney> ogra_: oh, got it, i assume he is in US
[10:08] <ogra_> germany 
[10:09] <ogra_> about 80km south of me 
[10:09] <cooloney> ogra_: that's close. how's you imx6 board.
[10:10] <ogra_> fine, idling on the shelf 
[10:10] <ogra_> i'm working on an automated qemu based testsuite atm ... so i havent looked much at real HW the last days
[10:15] <hrw> ok, time to reboot and check will usb3 drive work
[10:16] <cooloney> ogra_: i think ppisati probably have already sloved this issue in Ubuntu-3.5.0-208.14
[10:16] <ogra_> dunno, i havent seen the issue on that kernel ... but then i didnt do many RAM hungry tasks yet

[10:21] <cooloney> Signed-off-by: Andy Green <andy.green@linaro.org> Signed-off-by: Paolo Pisati <paolo.pisati@canonical.com>
[10:22] <cooloney> ogra_: i saw it set that min_free_kbytes to 32K as minium value
[10:24] <ogra_> ugh, ugly 
[10:25] <ogra_> we cant do that for omap i suppose
[10:25] <ogra_> might work for omap4 indeed
[10:26] <cooloney> ogra_: yeah, only on ti-omap4 branch
[10:27] <cooloney> actually there is no kernel config option for that default value. i think we can introduce one
[10:27] <ogra_> in mainline ? 
[10:28] <ogra_> on the pandaboard that bug isnt hitting as hard as on the beagle ... so that fix would have to go into master too
[10:28] <cooloney> if it is a right method to solve the issue, i think it is good for mainline
[10:28] <ogra_> k
[10:29] <cooloney> ogra_: right, but master also includes x86.
[10:30] <cooloney> probably have an option named CONFIG_MIN_FREE_KBYTES, if the min_free_kbytes < CONFIG_MIN_FREE_KBYTES, then let min_free_kbytes = CONFIG_MIN_FREE_KBYTES
[10:31] <cooloney> so we can set CONFIG_MIN_FREE_KBYTES as 32K in omap and omap4
[10:32] <ogra_> yeah
[10:32] <ogra_> sounds good
[10:32] <cooloney> ogra_: but maybe kernel maintainers will push that back as why not change that in userspace. heh
[10:34] <ppisati> ogra_: cooloney IMO that issue was never really resolved
[10:35] <cooloney> ppisati: ok, so even with the patches you applied from linaro, we still have this issue, right?

Like no mouse device, harddisk devices missing, network card missing, ... Did i miss something? I admit i'm not familiar how kernel stuff is packaged in Ubuntu ...
[14:39] <cking> bjf, can you add some more context? which kernel perhaps? ;-)

[14:40] <ppisati> diwic: it's not connected now
[14:40] <ppisati> diwic: e.g. does aplay go through the sound server? or does it check the hw device?

[14:42] <Worf> ogasawara: ok, it looks like that would be what i missed ... sorry for bothering ...
[14:43] <diwic> ppisati, yep. I would look in dmesg for errors
