Hi Jaroslav, 'Twas brillig, and Jaroslav Kysela at 07/01/10 14:59 did gyre and gimble: > The improved and more clean fix in now in my tree: > > http://git.alsa-project.org/?p=alsa-kernel.git;a=commitdiff;h=1250932e48d3b698415b1f04775433cf1da688d6 > > Note that you should apply these 4 patches (in reverse order): > > 4: ALSA: pcm_lib - optimize wake_up() calls for PCM I/O > 3: ALSA: pcm_lib - cleanup & merge hw_ptr update functions > 2: ALSA: pcm_lib - add possibility to log last 10 DMA ring buffer positions > 1: ALSA: pcm_lib.c - convert second xrun_debug() parameter to use defines > > Patch #3 should definitely fix problems with large avail or delay values > reported in PA.

Just wanted to ask about the status of this. We included the fixes in Mandriva cooker kernel for wider testing but some users are seeing issues. These four *seem* to be OK, but after also adding the "something must be really wrong" commit (http://git.alsa-project.org/?p=alsa-kernel.git;a=commit;h=7b3a177b0d4f92b3431b8dca777313a07533a710) folks started getting some errors. We also added the jiffies fix commit (http://git.alsa-project.org/?p=alsa-kernel.git;a=commit;h=ed69c6a8eef679f2783848ed624897a937a434ac) but that didn't seem to help. This is handled in our bug report here: https://qa.mandriva.com/show_bug.cgi?id=57010 For reference relating to comment 12: 2.6.32.3-1mnb: First introduced the above 4 fixes. 2.6.32.3-2mnb: included 7b3a177 2.6.32.4-0.rc1.1mnb: included ed69c6a Is there something more that needs done?
