Rather unusual for a console driver ;-)
fsck didn't find anything.
I checked a test11 tree and it seems that only the contents of the three
files was messed up, not the mtime/length. I can't rule out a hardware
cause but this doesn't look like a typical hardware problem to me:
mixing up data of different files.
Maybe SMP related because hardware is a dual PIII-450.
