This might be fixed also by position_fix=1, though. Yes, I had added this option after a regression in the previous kernel which causes the hd-audio thread to take 50% of a CPU. Eventually, it was fixed and not needed anymore. So I guess in the case of my laptop, this is not really a regression, because everything is fine with the default values. In the case of Frank, this looks more like a regression, or at least a bug to solve, because this happens with the default options. However, this report should be taken with care, because this happens on a 2.6.33.2 kernel made by Mandriva, containing many alsa patches of 2.6.34. Frank, how possible would it be to test a 2.6.34-rc4 kernel from Linus? If this bug is confirmed, Takashi, do you know any way to choose automatically position_fix=1 when needed?
