Re: Oops after resume from suspend

[dormando <dormando-uFjFfPRxV21eoWH0uzbU5w@public.gmane.org>]

For what it's worth, I'm seeing this too. However instead of a kernel 
panic usually the screen just locks, and the keyboard lights start 
blinking on the laptop :)

I have had success unloading both kvm_intel and kvm within the suspend 
scripts, then reloading after unsuspend.
