This still fails on me.

I've checked on another machine, with the same kernel but different
hardware and kernel configuration, and it does works fint. I don't
suppose any processor-specific assembly was added to the *-core, so I'm
inclined towards any conflict with this machine kernel's configuration.
FYI it's an AMD K6.

I'll try to backtrack in the *-core to determine when the problem
happened. Any other hints to hunt this bug down?
