Linux thunk 2.4.19-xfs #1 Sat Aug 3 12:52:09 CEST 2002 i586 unknown unknown 
GNU/Linux

As I said in my other mail, it takes some trying to get it to produce the
error. If I create different files with different sizes in different ways
the problem *will* get triggered. I can reproduce it on two machines, one
running 2.4.19-xfs (p200mmx, SCSI) and one 2.4.19-rc2-xfs (Athlon XP, IDE).

Also of note may be that I'm running it with the ngpt futex patch and the
O(1) scheduler patch.
