Latest kernel with this patch applied locked up one of my DragonFly
box with SiS-based mainboard. It doesn't lock up with a simple
test like
dd if=/dev/zero bs=1m of=BIG
but with
cp -r /usr/ports/ .
locks up the machine. No alt-esc-del combo works, just waiting to be
reboot. I tried the same tests several times on a kernel without the patch,
and I couldn't reproduce the lock up.
This is a UP kernel. I don't have an SMP-capable box with IDE disk around
me right now.
