As of yesterday, my machine is booting and running beautifully off the
BusLogic 747 and the SCSI drive.  I'm approaching a full day of uptime:
 8:29am  up 19:35,  6 users,  load average: 2.86, 3.02, 2.91
running X, a make in /usr/src, a build of emacs 19.22 and a 9600 baud
kermit connection the entire time.

There are some crusty parts in the current bt742a.c driver on current,
and I'm working on a bastardization of the current driver, Julian's new
SCSI driver from magnum, the Mach 2.5 driver, and the FreeBSD driver.
(Actually, they're all just different version of the same thing, but
the newer ones have some fixes for a big problem.)

The problem had to do with allocating the mailbox and ccb structs just
anywhere in kernel memory, which means they could cross a page
boundary without knowing it.  This can prove to be fatal, as in my
case.  The fix is to make sure they start at a page boundary and don't
get too big that they cross over into another.  Updated driver coming
RSN.

It was until I broke my system with the new SCSI hardware. ;-)  I'll
try to get it back up soon, though I may only update it weekly,
instead of daily like I was doing.
