| infinity | hallyn: Can you try that with 3.8? | 01:01 |
| infinity | hallyn: (or try mounting something inside that isn't a tmpfs) | 01:01 |
| infinity | hallyn: In the current 3.7 in the archive, there's a tmpfs leak that could be, perhaps, not helping here. | 01:02 |
| hallyn | infinity: we confirmed with http://kernel.ubuntu.com/~rtg/Ubuntu-3.8.0-0.1/ | 01:35 |
| hallyn | can't do an upstream tree as we need overlayfs | 01:35 |
| hallyn | it shouldn't be tmpfs since you don't have to mount a tmpfs to trigger it | 01:36 |
| infinity | hallyn: Okay, I just saw your script used a tmpfs. But if it's still there in 3.8, it's not the bug I was thinking of anyway. | 01:41 |
| hallyn | infinity: yeah there are commented lines in the script which can be used as an alternate to the tmpfs mount - which mount devpts. i added tmpfs bc stgraber asked if devpts might be the trigger :) (it's not) | 02:02 |
| MikeMin | Did anyone have any luck with http://rankone.us? | 02:05 |
| infinity | apw: When you wake up, we need a new linux-signed to match the current linux (in raring). | 04:29 |

| henrix | are you guys fine with that? | 10:04 |
| cking | henrix, can I stall on this for 20 mins while I answer an email concerning this fix | 10:06 |
| henrix | cking: sure :) | 10:06 |
| cking | henrix, i'm fine with it, apw, any thoughts? ^^ | 10:43 |
| apw | yeah it is very very unlikely to cause problems and if it does it means you don't keys keys or something for a small number of machines | 10:44 |
| apw | and the potential upside, our CDs are safer, seems worth that risk to me | 10:44 |
| henrix | apw: cking: ack, thanks | 10:48 |
| henrix | i'll add a comment to the bug and proceed to testing | 10:48 |
| cking | henrix, apw explained it very succinctly | 10:48 |
| henrix | yep, i'll write that down on the comment :) | 10:49 |
| henrix | thanks | 10:49 |

| smb | apw, did I not see you talk about this recently...? That we have some event there not upstream | 11:30 |
| apw | jodh, yes we have a patch for those trace points | 11:31 |
| jodh | apw: ok, thanks. I've updated the bug, but sounds like someone may have to bisect our patchset then. | 11:31 |
| apw | jodh, i am told actually there are now generic syscall ones | 11:31 |
| apw | jodh, wich are hinted at in our patch | 11:32 |
| jodh | apw: if you can send me some details, I'll take a look, but currently ureadahead is broken on seemingly everything but armhf | 11:32 |
| apw | jodh, i'll poke it first, it could well be the patch is no longer working | 11:35 |
| apw | it is about time someone knew how this worked again | 11:37 |

| ogasawara | henrix: hi, when is the 3.2.0-36 kernel in precise-proposed getting promoted to -updates? today? | 13:00 |
| ogasawara | henrix: oh wait, or is this the one we're letting this one bake an extra 3 weeks for the point release | 13:03 |
| herton | ogasawara, it still has next week for testing on the schedule, waiting on security-signoff/certification-testing right now. I believe will be promoted some time next week | 13:08 |
| herton | ogasawara, indeed, from what I remember this will be the one for the point release, not sure if it will be on hold or not | 13:09 |
| ogasawara | herton: ok thanks. I assumed we'd still promote it to -updates, we just wouldn't turn the crank on a new cycle. | 13:10 |
| ogasawara | bjf: is my assumption correct ^^ | 13:11 |
| herton | ogasawara, yes that's correct | 13:11 |
| ogasawara | herton: perfect, thanks | 13:11 |
| * henrix -> lunch | 13:21 | |
| apw | jodh, ok this is part kernel, part ureadahead issues, am testing the fixes now | 13:31 |
| jodh | apw: thanks - sounds intriguing :) | 13:45 |
| apw | jodh, deprecation of an interface we are using for ureadahead and change of type affecting the interfaces for open in the kernel | 13:48 |
| apw | i'll get some patches out shortly | 13:48 |
| jodh | apw: thanks. I wonder how are we going to stop this sort of thing happening in the future though? Is there a list of deprecated interfaces that we could grep the archive for say? | 13:51 |
| ogra_ | one good step would be more detailed error msgs in ureadahead | 13:52 |
| ogra_ | it took me half a day to find the issue on the nx7 ... if it woulld have told me "cant open /sys/foo/bar" that would have been easier than having "exited with startus 5" | 13:53 |
| jodh | yeah, I think that + mountall could do with some 'nose-cone polishing'. I've written a crude DEP-8 test for ureadahead that would detect the bug we're discussing, but if we can catch incorrect syscall usage before apps hit the archive, all the better ;) | 13:53 |
| ogra_ | ++ indeed | 13:54 |
| jodh | ogra_: strace :) | 13:54 |
| ogra_ | yeah, thats what i resorted to indeed | 13:54 |
| sforshee | apw, what was the bug you were seeing with the wl driver? | 14:04 |

| apw | ogasawara, i am considering whether to upload this ureadahead change as it is not an abi bumper, and we are so far for -rc4 | 16:12 |
| ogasawara | apw: works for me | 16:12 |
| apw | ogasawara, rtg, have anything in the pipeline for raring ? | 16:13 |

| tseliot | apw: hmm... let me check | 16:34 |
| tseliot | apw: did it use to work? | 16:38 |
| apw | tseliot, i doubt i had ipv6 when i first switched away from wl | 16:38 |
| apw | tseliot, and generally i use brcmsmac to give it some testing | 16:39 |

| tseliot | apw: does it help if you do something like this? System Settings -> Network -> Wireless -> [select your network(s)] -> Options... -> IPv6 Settings -> Method: Ignore | 16:40 |
| apw | tseliot, if i rmmod wl and modprobe brcmsmac it works fine, so i assume system level is configured | 16:41 |
| apw | correctly | 16:41 |
| tseliot | apw: what happens if you reinstall the previous upstream release? | 16:42 |
| apw | it doesn't work with v3.8 right ? | 16:42 |
| herton | hggdh, done | 16:42 |
| hggdh | herton: thank you | 16:43 |
| henrix | hggdh: sorry, i should have done that 2 days ago... | 16:43 |
| hggdh | herton: no prob, I just wanted to be sure I was Doing The Right Thing ;-) | 16:44 |
| tseliot | apw: right, I didn't port that driver to 3.8. Wait does 3.7 make any difference with this issue? | 16:44 |
| apw | tseliot, dunno to be honest | 16:44 |
| apw | tseliot, ask me in the bug to remind me, i've rebooted this latop 10 times today for other kernel issues, and frankly i cannot cope with rebooting again today | 16:45 |
| hggdh | apw: for the record, bcmwl V5 only works with 3.7 up to, and including, 3.7.0-5 | 16:45 |
