Also, there should be some relevant messages from the driver before entering this point. Could you check it? Another questions: - how often does it happen, how reproducible is it? - is whether it's a regression in 2.6.31 -- have you ever gotten this in the earlier version? There are a few changes in the codec communication code since 2.6.30, but I don't see any obvious problem in them... thanks, Takashi ^ permalink raw reply [flat|nested] 5+ messages in thread

But; unfortunately, I wasn't able to reproduce it. It happened when I was playing some HD movie content and it only happened with this (2.6.31-rc8-git1-rt9) kernel release. All the previous versions, that I tried, don't have this issue. Just I discovered this warning in dmesg. Maybe, it can give some clue : \ [ 24.197420] hda-intel: azx_pcm_prepare: bufsize=0x10000, format=0x31 [ 24.197431] hda_codec_setup_stream: NID=0x2, stream=0x5, channel=0, format=0x31 [ 24.219842] hda-intel: IRQ timing workaround is activated for card #0.
