Erm, it is caused by _non_-hardclock() interrupts being disabled for for too long. This is normal for non-slow hardware connected through a slow interface (some IDE confirguations, ISA ethernet) and for buggy software like PLIP. The bug is inhibited by hardclock interrupts being disabled for far too long, since the timecounters normally don't rotate unless hardclock() is called.
