On the Linux box in question, I was using JFS, which has had the mixed
reviews, lately, that on the one hand, it _appears_ to be a tad faster
than all the others, but that has been, on the other hand, associated
with systems hanging up and crashing, under load.

The latter bit is a _really_ big caveat.  On that particular machine,
I have a nicely repeatable "test case" where I can do a particular set
of "system load" that consistently takes the system down, to the point
of having to hit the "big red button."  If I could point to a clear
reason why it happens, I'd be a much happier camper.  As it stands, it
is a bit nebulous whether the problem is:
 a) Hardware drivers,
 b) Flakey hardware (which Linux 2.6.1 copes with a lot better than
 c) Flakey 2.4 kernel,
 d) Problem with JFS,
 e) Something else not yet identified as a plausible cause.

If I could say, "Oh, it's an identified bug in the Frobozz RAID
controller drivers, and was fixed in 2.6.0-pre-17", that would help
allay the suspicion that the problem could be any of the above.
