Bug#516014: xorg: Since upgrade to Lenny on 2/15, Xorg frequenly spikes CPU to 100%
I got exactly the same bug - sometimes (appr. one time per 5 hours)
xorg process uses 100% of CPU's core while it draw something (like
window scrolling or any changings on screen). Xorg version is 1:7.3+19
(1:7.3+18 did the same).
I had ATI Radeon X1600XT with hand-made cooling system (I mean it was
not so good). After appearing this bug I tryed to change cooling
system to good one (two huge radiators with big cooler). So, bug
completly disappeared.
So we have solutions, but we don't know the reason. I mean we don't
know place in the source code, which provoke this bug. Bad cooling is
bad of course, but xorg should say about it with some other phrases...
I think, people who still have this bug should run something like
profiler for xorg process to locate this place in code. Anyway, corg
developers interested in this.
