This particular problem is BIOS related; what happens is that, because the
default code for the disk driver doesn't zero out the disk structure, 386BSD
believes it has already brought the disk up.
If a warm boot (3 finger salute) doesn't execute a routine to zero the
memory, you hang when it sees a properly filled out struct and believes
the disk already "there".
One of Chris's (cgd@agate.berkeley.edu) earliest patches fixes this
problem by zeroing all malloc'ed memory in the wd driver. This patch
is part of the patch kit.
The problem is most prevalent on laptops, but does show up on other
boxes occasionally.
