So, what do you see on the screen when this locks up?  I think I know
where this is, but i'd like to confirm.

Is the IDE controller (wdc) and the disk probing properly?  You can hit
Scroll-Lock and use the arrow keys to scroll back.

This sounds like the disk isn't probing properly.

That's odd.  I wonder if the firmware on your disk is corrupted or is
buggy.

The problem with big disks is that after about 4 gigs, the access times
start hurting your performance.  You can get better performance by using
two 4 gig disks, which allows you to overlay commands on each disk
(assuming you're using SCSI or one IDE controller per disk).
