I believe that was the one I experienced a while back. I still have
that debugging kernel ready to catch it, but it hasn't happened again.
Maybe I'll get around to torturing the filesystem one of these days.
I don't think there's anything really special about my setup, though.
I have two 4.3GB IBM DCAS-34330W's on a NCR 53C875 based controller.
Bunch of data to help you see what I have follows... Keep in mind
this system is never on for more than a day or two, or else I wouldn't
be able to sleep. :-) It has also only been on 4 hours now, almost
entirely idle, so the 'writes:' numbers are low.

I also noticed something kinda funny up there in the dmesg. See where
it reports scbus0 target 0 lun0 as 10.0MB/sec, then says the same
device (sd0) is 40.0MB/sec a few lines later? Same with sd1.
