I have a Toshiba Satellite A665-S6086. It has Intel everything (graphics, processor, wifi).
It suspends fine. However, probably one out of every ten times, resuming fails. Just a black screen, sometimes with a cursor, requiring a hard reboot.
I can get it to fail reliably if I plug in the ac adapter while it's sleeping and then try to wake it up.
There is nothing in /var/log/messages of any interest except that it doesn't write anything about the resume process when it fails.
I tried removing autodetect hook from mkinitcpio and adding resume hook, but neither helped.
I am running laptop-mode-tools.
How do I begin to debug this?

Anything in /var/log/{pm.log,pm-suspend.log} ?

Here are the last lines of each file:
pm-powersave.log
Running hook /usr/lib/pm-utils/power.d/laptop-mode false:
pm-suspend.log
Running hook /usr/lib/pm-utils/sleep.d/00powersave resume suspend:
So it looks like something just didn't finish... Most other lines in those files have "success" after the colon.
I tried setting intel_idle.max_cstate=0 in my kernel line in Grub, but that didn't fix it.
EDIT: Neither did noapic parameter
