Re: PROBLEM: ACPI crashes (2.6.2-rc2-mm1)

Looks like this didn't get through last night. Let me try it again.

Hi,

Just wanted to add my experience. I was able to suspend to disk and
resume just fine from a console with the following configuration on the
Gateway 200X.

kernel 2.6.1
agpgart module loaded
intel_agp module loaded
i830 module loaded
swsusp compiled into the kernel
ACPI sleep states compiled into the kernel
suspend with 'echo 4 > /proc/acpi/sleep'

When I tried this after starting X with startx, I got the reboot loop
described by others. I figured I'd give it a shot, since the AGP modules
didn't interfere with the console suspend/resume. Ah well.

Interestingly, starting X and then dropping back into a console
caused problems, too. I didn't get stuck in a reboot loop, but the
resume just hung. It did get past the 'Waiting for DMA to settle down'
message, though. I can't remember now exactly what it said, but it
seemed to be mostly done. I had to do a hard reboot to get it back, and
then I had to do the 'noresume; mkswap; swapon' routine.

I haven't tried unaccelerated X, since the AGP modules seem to be
loaded regardless of what I do (remove the agpgart alias in
/etc/modules.conf, remove X from default runlevel, etc) and I cannot
unload them. I guess I should try compiling a kernel without AGP support
at all next.

Thanks,
Greg
