Uh oh. It's not the kernel. It's your Tomcat III. I've had some
strangeness myself. I've apparently killed three Quantum bigfoots, such
that not even the BIOS could autodetect them anymore (and they died
_fast_). Also on another machine (another Tomcat), we had some real
filesystem weirdness with two IDE MD'ed drives where files would become
directories and other strangeness, but only a specific area of the fs. I
eventually decided to just move everything to a SCSI drive and everything
has been peechy since. Fortunately the other machine didn't destroy the
drives, as they work fine in other machines now. I just thought (until now)
that it was just bad luck and IDE's overall cheapness and worthlessness.

In the first machine also, when I had two drives on the same primary
controller and attempted to copy files from one to the other, it would slow
way down, produce IDE errors and eventually lockup the machine. Attempting
to do anything with the bigfoots would also produce the same results only
almost instantly.

The bigfoots BTW, seemed to "die" when they were the secondary slave.

Something stinks in Tomcat country...
