Seconded.

Exactly the same symptoms (bzip2); the culprit turned out to be memory.

That's when I wrote memburn (http://v.iki.fi/~vherva/memburn.c) for quick
testing without a boot (it did find the problem) and I then verified the
problem with memtest86 (http://reality.sgi.com/cbrady_denver/memtest86/).
You do have to run either for hours, propably for days to be sure.

The box has now ran perfectly for a year or so with the BadRam patch from
Rick van Rein (http://rick.vanrein.org/linux/badram/).
