I recently upgraded to 6.2 release (i386) on my desktop workstation, and
I'm experiencing occasional lockups that require restarting X to resolve.
I can ssh in to the box and kill the process and force a restart, but the
desktop is completely unusable - both mouse and keyboard don't function -
so I can't restart X with Ctrl-Alt-Bkspc. When I ssh in, performance is
normal and top doesn't show any unusual memory or CPU usage. PID974 was
the pid for X.
I found these errors in /var/log/messages:
Dec 12 09:36:51 utd59514 kernel: error: [drm:pid974:drm_lock_take] *ERROR*
1 holds heavyweight lock
Dec 12 09:36:51 utd59514 kernel: error: [drm:pid974:drm_lock_take] *ERROR*
1 holds heavyweight lock
Although these showed up on the 12th, the desktop just locked up a few
minutes ago, so they *may* be unrelated. I tried unloading drm (kldunload
drm.ko), but that failed.
When I grep the Xorg log I see these errors:
root@utd59514# grep EE /var/log/Xorg.0.log
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(II) Loading extension MIT-SCREEN-SAVER
(EE) RADEON(0): Unable to write to DVO Slave 112.
(EE) RADEON(0): Unable to write to DVO Slave 112.
(EE) RADEON(0): Unable to write to DVO Slave 112.
I don't know if these are related to the problem either. I'm wondering 1)
has anybody else experienced this problem and 2) does anyone have any
suggestions as to where to start looking for the answer?
