I just had one of those today as well, though it was a page fault 02
from interrupt, ie. a kernel write not read.

The box is a 440BX with 2 400MHz p2's. My kernel is a 2.1.114-vger and
I also have a 53c8xx in the box (53c896 to be precise) at the moment,
in fact it happend while running some serious reading data off the
network writing to disk.
