OS/2 also had the cache problem.  In running with the cache disabled, OS/2 is
fine and FreeBSD has the problem with the disk hangs.  So there are two
entirely seperate problems, with problem #2 being this disk controller problem,
and problem #1 being a cache hardware problem - which is not relevant if the
cache is disabled.  Sorry for the confusion.

An easy question for you to answer - can I grab the current wd.c file, plug it
into the 1.1.5 kernal and stand any chance of it working?
