I was having what sounds like that exact problem on a _non_SMP_ machine
with a 2.0.32(?) kernel (sorry I'm at work and the machine's at home and I
can't think of which kernel it was off the top of my head.) If anybody's
interested in specific details of the problem machine/kernel, I can provide
them. I've been trying to hunt down the problem for months to no avail,
and it seems to have gone away this week (installed Linux from scratch with
a newer distribution/kernel on a non-1024+ cylinder HD).
