| 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 | 08:33 |

| cooloney | ppisati: nice trip for vacation. heh | 08:46 |
| xnox | hrw: I am all ears, since I am experiencing similar. But for me it might be lvm related. | 08:47 |
| * 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 | 08:48 |
| hrw | xnox: disk will be mostly used with usb2.0 laptop but for future use I prefer usb3.0 ;) | 08:49 |
| 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. | 08:50 |
| cooloney | ppisati: if you need me take care of some ARM stuff during your vacation, please let me know | 08:52 |
| ppisati | cooloney: feel free to chime in, the ti-omap4 lp bugs page is always looking for some love :) | 08:59 |
| 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 | 09:49 |
| 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 | 09:50 |
| 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 | 09:51 |
| ogra_ | but ask marvin24, he was really into that bug for a while | 09:52 |
| cooloney | ogra_: ok, cool | 09:52 |
| 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 | 09:55 |
| ogra_ | also its somnething that looks like the kernel should set it right | 09:56 |
| ogra_ | instead of userspace with hackish detection scripts | 09:56 |

| hrw | argh... | 09:57 |
| hrw | how to disable all abi checks etc? I want to test some usb3.0 patches and kernel compilation drives me mad | 10:00 |
| cooloney | ogra_: looks like marvin24 is not online | 10:07 |
| 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 | 10:08 |
| ogra_ | about 80km south of me | 10:09 |
| cooloney | ogra_: that's close. how's you imx6 board. | 10:09 |
| 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 | 10:10 |
| hrw | ok, time to reboot and check will usb3 drive work | 10:15 |
| 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 | 10:16 |

| cooloney | Signed-off-by: Andy Green <andy.green@linaro.org> Signed-off-by: Paolo Pisati <paolo.pisati@canonical.com> | 10:21 |
| cooloney | ogra_: i saw it set that min_free_kbytes to 32K as minium value | 10:22 |
| ogra_ | ugh, ugly | 10:24 |
| ogra_ | we cant do that for omap i suppose | 10:25 |
| ogra_ | might work for omap4 indeed | 10:25 |
| cooloney | ogra_: yeah, only on ti-omap4 branch | 10:26 |
| cooloney | actually there is no kernel config option for that default value. i think we can introduce one | 10:27 |
| ogra_ | in mainline ? | 10:27 |
| 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 | 10:28 |
| cooloney | ogra_: right, but master also includes x86. | 10:29 |
| 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 | 10:30 |
| cooloney | so we can set CONFIG_MIN_FREE_KBYTES as 32K in omap and omap4 | 10:31 |
| 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 | 10:32 |
| ppisati | ogra_: cooloney IMO that issue was never really resolved | 10:34 |
| cooloney | ppisati: ok, so even with the patches you applied from linaro, we still have this issue, right? | 10:35 |
