Weird. I just can't reproduce any of your problems, neither on the
tipb with highmem & lots of RAM, or on the wallstreet with no highmem
and little RAM (thus swap)...

I've been running with preempt for a few days now without trouble.

What else are you using ? I suspect something like MOL may have troubles
with preempt for example...
