[Bug 479296] Re: Karmic: frequent freezes

[Mcflan]

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.
