Comment 25 for bug 479296

Hi Daniel and all, I'm back just to report that, since I installed linux-backports-modules-alsa-karmic-generic, the issue is no more reproducible at my end. During last week, I only experienced 2 freezes that were somewhat different from those frequent ones already described: one didn't involve any audio, plus I could move the mouse pointer (like described by Simon Nuttall at #7, for example), but nothing else worked; the other happened after logging out, before I could enter my password again (no mouse moving here). No revealing trace was left in the log these times, before freezing.

All in all, I can say things are much better now, although I'm not entirely sure that audio was the only cause of the issue, although apparently a major one (at least in my case). Also, I keep reading the same lines in the System Log (as detailed in my report), although I don't worry any longer, after you wrote that the ratelimit messages are not errors. But what about:

Nov 3 02:47:30 ECO pulseaudio[1564]: ratelimit.c: 153 events suppressed
Nov 3 02:49:19 ECO kernel: [59669.083978] [drm] LVDS-8: set mode 1024x768 d
Nov 3 02:49:21 ECO kernel: [59671.086380] [drm] DAC-6: set mode 640x480 0
Nov 3 02:49:22 ECO kernel: [59671.576399] [drm] DAC-6: set mode 640x480 0
Nov 3 02:49:22 ECO kernel: [59672.002693] i2c-adapter i2c-1: unable to read EDID block.

They always come together, although I clearly don't understand their origin, nor could I say that they are related to one another. Since 640x480 reminds me of the display resolution (mine is in fact 1024x768), does it have anything to do with the Graphics Device? And may it be responsible for the freezes? Many thanks again.
