Comment 6 for bug 521775

Well, here are some more errors from Karmic

Feb 22 11:10:14 mini-laptop pulseaudio[2103]: ratelimit.c: 262 events suppressed
Feb 22 11:10:14 mini-laptop kernel: [85247.597134] hda-intel: spurious response 0x0:0x0, last cmd=0x224011
Feb 22 11:10:20 mini-laptop pulseaudio[2103]: ratelimit.c: 79 events suppressed

This is a fresh reinstall, and I would have said it was a hardware issue, but I have none of those running Jaunty.

It also took 24 hours till 'hda-intel: spurious response' appeared and sound stopped working.
