RE: Another CPU slows to a crawl after resume from suspend

My CPU does this and I originally put it down to the suspend-resume cycle.
I've now found that it doesn't behave like this if the pcmcia modules are
not loaded.
My Bios is also the Phoenix 6.0 Bios.

You are right about the utility for switching the CPU speed - perhaps via a
dummy module if kernel access is required.
