X Core Dumps

Hi,

I've been having X core dump on me when I resume from sleep
on my
X40.  It's not completely reproducible, but I managed to
get a core
dump: http://cyth.ne
t/~ray/tmp/Xorg.core.gz.  Please let me know
if there is anything else I can do to help.

Please try to extract a stack trace yourself out of gdb. I
don't have 
your X server binary...

Usually X crashes on resume on the X40 because the graphics
engines 
locks up. The X server detects it and tries to exit cleanly,
but 
sometimes fails.

This has been identified by Alan Houriane, the main
developper of the 
i810 driver by a race problem between the APM BIOS that
tells the OS 
that the machine just woke up and the video BIOS which has
not 
completely restored the graphics chip set. He mentionned
ACPI as a 
possible way to "fix" that, but I think OpenBSD
is far from having ACPI 
suspend/resume support.
