apwdiwic, yo ... this SND_DEBUG thing, is this something you would make use of if it was turned on?10:53
diwicapw, rarely, but it happens11:13
diwicapw, heh, by your latest email it seems we're following upstream's recommendations11:14
diwicapw, or, its default but not its recommendation, which is a bit contradictory11:14
apwdiwic, yeah, so as you are our audio expert we would prefer to be guided by you, if you see value in it, file a bug and let me know the number and we can prototype it in saucy11:31
diwicapw, ok. I'll await what Takashi says about it11:32
apwdiwic, great, i will promptly forget until we hear from you11:32
diwicapw, ack11:32
apwdiwic, i think he has already replied in the positive, so file me a bug11:33
apwand i'll get it in the next saucy 3.9 upload, i am keen to upload it as it has a security patch sitting on it11:34
apwdiwic, there is a new option exposed by SND_DE11:40
apwdiwic, there is a new option exposed by SND_DEBUG, SND_PCM_XRUN_DEBUG ... do we want that on or off11:40
diwicapw, I guess the value is either that we're testing code that others are not testing (QA!), or that we're sticking with what SuSE is doing (less bugs for us!)11:41
diwicapw, I've actually fixed a bug once that only occurred with SND_DEBUG off11:41
diwicapw, let me check XRUN_DEBUG and see if it has any performance impact11:42
apwdiwic, we want less bugs i suspect11:42
diwicapw, xrun_debug can actually be even more helpful11:46
diwicapw, I say let's go for both11:46
diwicapw, bug 118774411:47

psivaajsalisbury: Just curious about the ETA of a fix for bug 1181315. 13:26
psivaaThis bug is causing a couple of daily smoke test failures and it's not being assigned to anyone.13:26
psivaaWould also help to get that assigned. thanks13:26
jsalisburypsivaa, I'll start the bisect now.  It would be good to test v3.10-rc4 as well, just to confirm it's not fixed in mainline.13:28
jsalisburypsivaa, I'll post a link to v3.10-rc4 in the bug13:28
apwdiwic, ack13:34
apwogasawara__, i am thinking i would upload a 3.9 saucy, to get the pending security fix out13:34
ogasawara__apw: ack13:36

apwogasawara, and i'll upload the unstable to preproposed13:41

henrixjsalisbury: its a linus tree sha114:18
henrixjsalisbury: if you check the commit body, it refers to bug that seems to be the same one14:19
jsalisburyhenrix, cool, thanks for finding14:20
henrixjsalisbury: np14:21
henrixjsalisbury: let me know if you want me to build a test kernel14:21
jsalisburyhenrix, I'll build a raring kernel with that commit and post it to the bug14:21
jsalisburyhenrix, heh, 14:21
henrix:)14:21
jsalisburyhenrix, it's up to you.  I don't mind doing it14:21
henrixjsalisbury: and it looks like we'll hit the same bug on other kernels as well (at least Q)14:22
henrixjsalisbury: heh, looks like the bug reporter has already found the fix himself :)14:23
henrixand he confirms it fixes it, so no need for a test kernel ;)14:23
jsalisburyhenrix, great14:23

jsalisburyhenrix, it looks like a87783699b23395c46bbeeb5d28f6db24897bf26 was sent to stable14:27
henrixjsalisbury: yep, that's how i found it :)14:27
jsalisburyhenrix, :-)14:27
henrix_bjf: is it too late in the sru cycle to add this fix into the kernels (P, Q and R)?14:28
psivaajsalisbury: I've just updated bug #1181315 to say that it is still present in v3.10-rc4 as well. 14:29

jsalisburypsivaa, cool.  Thanks.14:31
jsalisburypsivaa, I started a bisect, so I'll have a test kernel for that shortly.14:31
jsalisburypsivaa, I also identified two commits in the changelog from 3.8 to v3.9-rc1 that may be suspect. I'm also going to post  a test kernel with those two commits reverted as well.14:32
psivaajsalisbury: ack, could test that when it's ready14:33
apwjsalisbury, sounds like you are haivng fun there14:33
jsalisburypsivaa, copying it now.  posting  a link to the bug14:34
