I have a FC2 system whose X11 has locked up after sitting on a
screensaver overnight. I can still get into the system via ssh, but I
cannot vt switch away from the locked up X11. The X process is taking
up all the CPU:
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
root 23040 97.7 5.2 67488 20248 ? R May 22 1-16:02:50 /usr/X11R6/bin/X :0 -audit 0 -auth /var/gdm/:0.Xauth -nolisten tcp vt7
strace shows it in a tight loop:
select(1024, [8], NULL, NULL, {0, 0}) = ? ERESTARTNOHAND (To be restarted)
select(1024, [8], NULL, NULL, {0, 0}) = ? ERESTARTNOHAND (To be restarted)
select(1024, [8], NULL, NULL, {0, 0}) = ? ERESTARTNOHAND (To be restarted)
Xorg.0.log shows this repeating error:
(EE) RADEON(0): GetBuffer timed out, resetting engine...
(EE) RADEON(0): Idle timed out, resetting engine...
(EE) RADEON(0): GetBuffer timed out, resetting engine...
(EE) RADEON(0): Idle timed out, resetting engine...
(EE) RADEON(0): Idle timed out, resetting engine...
(EE) RADEON(0): Idle timed out, resetting engine...
(EE) RADEON(0): Idle timed out, resetting engine...
...
How can I go about debugging this so I can make a meaningful bug
report? What debuginfo packages and gdb version do I need?
