Comment 67 for bug 479296

I have a similar problem with occasional crashes on Karmic (9.10). Sorry to say "me too" but I'm stumped on this one. Don't remember having this problem with Jaunty.

System hangs sometime occur a few seconds after selecting a new track in Rhythmbox (but can happen randomly at other times). Music carries on playing until end of track, mouse moves ok but everything else is stuck, including caps lock. Only way out is to use magic sys-request key to put keyboard into raw mode then 3-finger salute or sync-unmount-boot. However, graphics chipset status is evidently fubar because system must be physically power-cycled otherwise it will re-enter the same (hung) state once ubuntu starts X (gdm) again.

I also get pulseadio ratelimit messages but I think they might be a coincidence. Annoyingly, there are no other messages in the system log at the time of the crash.

Running Karmic on a toshiba laptop (Satellite Pro A10) with Intel sound and video (i810/i915) chipset.
