Re: cx88 sound does not always work (Re: [PATCH v2.6.38 resend 0/7] cx88 deadlock and data races)
Update: I noticed I was using the desktop kernel this time, and reinstalled the default kernel. The audio now works fine (once this patch is installed). Works every time. This rings a bell, like I've had to do this to a system in the past. I don't really understand what desktop vs default kernel would have an effect on the drivers - from what I can read there doesn't seem to be anything in there.

I don't believe so, same hardware I have linux Suse 11.1 kernel 2.6.27 with custom built drivers from v4l (July 2009). This works 100%.

Once it is started it stays, getting it started is not reliable. Could you give details? What card do you use? Does it show up in lspci -vvnn output (and if so, could you show us)? What kernel version? Could you attach your .config and dmesg? Was this reported on bugzilla before? How does sound not working manifest itself? How do you go about getting it to work? See the REPORTING-BUGS file for hints.

Ben Hutchings provided an initial patch[1] to fix that, and Andi Huber helped a lot in finding races that patch had missed. Ben requested that I take authorship of the series, so I've done so. These patches have visited the list twice before[2], towards the beginning of this month. No feedback from maintainers or reviewers --- I'm beginning to wonder if I have the right list. Luckily two people[3][4] experiencing this problem on bugzilla were kind enough to test the series and found it worked okay. Patches are against v2.6.38 (but they do not conflict with anything in media-tree/staging/for_v2.6.40). The intent is to include them in v2.6.40 if possible.
