Actually, I can reproduce the exact same problem by just dd'ing a lot from
/dev/zero to some other file on a UDMA/33 disk on my K6-2 350 with an Asus
p5a motherboard (ali aladdin chipset). This is on 2.3.99-pre6. I did not
notice this on pre5

One strange thing is that with pre6, 16k of my swap space is used. With
256MB ram, I usually use no swap at all. Right now free(1) tells me that I
am using about 34MB ram (buffers/cache included), but 16k swap is used
nonetheless.
