Xorg eats my CPU
Hi,
I am running (up to date) Debian unstable on my laptop, it has a
Radeon IGP 340M graphics chip. For the last month or so I am seeing
the Xorg process gradually gobble up more and more CPU, up to 30/40%
and in some cases 99%.
Even X on its own seems a little sluggish, e.g. when I change windows
the gnome icons take a fraction of a second to appear in the new
window.
But the big CPU problems are seen when I run mozilla-firefox, since
usually when I kill firefox Xorg recovers. I don't see any messages
in logs that might explain the behaviour and I can't find any related
bugs filed against Xorg.
Here is the output from the top of top:

(Hope that shows up OK)
Does anyone have any idea what bug this might be? Or clues on how I can
track it down further? I don't really have enough information to file
a bug report yet ....
Thanks for any advice / help
Kevin
