Description of problem:
I get a hard lockup when logging out of the desktop running dual head
from a Matrox G550. Bootup, login and running of X dual head for hours
is okay. It's just when I logout. The system does not seem to even get
to gdm again because the background remains visible at the hang.
CTL-ALT-Backspace doesn't work because mouse and kbd are dead.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Boot into X or boot to RL3 and startx
Actual Results: System hang. Have to fsck the filesystem on the way
Expected Results: clean logout and gdm display
I saw this repeatedly until one of the hald updates just before Christmas.
My sypmtoms (observed via a remote session) were that the hal daemon
appeared to be spawning many processes trying to read contents of my
(empty) CD writer, and that hung the logout. If I left it for someting
like 30 minutes, it logged out fine. Logging back in repeated the problem.
Hasn't happened now for some weeks.
Setting status to "RAWHIDE" as the problem aparently no longer
occurs as mentioned in comment #1 above.
