Public bug reported:
Binary package hint: xserver-xorg-video-ati
New after upgrading to jaunty (no problem with intrepid on this
machine):
X will work for a while, but eventually (could be minutes or hours after
booting) it suddenly jumps to 90+% CPU. I can still move the mouse, sort
of (it's laggy and jumpy) but mouse clicks don't work, keyboard events
don't work, and apps apparently stop redrawing.
This doesn't seem to be in response to anything in particular -- nothing
intensive going on in Firefox, no flash or animations, all other windows
are pretty simple (xterm, xchat, emacs).
Video card (from lspci):
01:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200 SE]
(rev 01)
01:00.1 Display controller: ATI Technologies Inc RV280 [Radeon 9200 SE]
(Secondary) (rev 01)
I can still ssh in from another machine, but I can't kill (even with -9)
the window manager or Xorg -- killing has no effect. All I can do is
reboot.
If I attach to the Xorg process and check every few seconds, the trace each
time looks like:
(gdb) where
#0 0xffffe430 in __kernel_vsyscall ()

I see xserver-xorg-video-ati-dbg in the package list, and would be happy
to install it if it would help.
