Very good sugestion, thank you, that is obviously it and it didn't cross
my mind.

It is on irq11 (devices cbb0, cardbus and ohci0++, whatever ++ is).
53000 interrupts per second... That might just slow down even an Athlon
64.
I'm going to disable cardbus first and then ohci. Isn't there a specific
command to keep an interrupt source quiet?

This should have crossed my mind. When I was a kid, in DOS days, I once
increased the clock tick rate on DOS with similar effects.

Good thing that witches don't exist. Felix qui potuit rerum cognoscere
causas.
