My setup:

Mac SE/30, eight megs physical RAM, twenty megs of swap, SBC SCSI driver

Last night I snagged the 1.3_BETA binary snapshot, and compiled a new
kernel. (My last kernel was semi-early 1.3_ALPHA.)

My untarring went without a hitch, and my new kernel was in place. I
rebooted, and things seemed to be going well for a bit, until my machine
dropped into the debugger. For lack of a better way to capture what was on
the screen, I simply wrote down a lot of it:

root on sd0a dumps on sd0b
trap: type 0x0, code 0x75d, v 0x8ff003
kernel: Bus error trap
pid=0, pc=00088D0C, ps=2204, sfc=1, dfc=1
Registers:
	[ I didn't copy this info down - I will if needed. ]
Kernel stack (000DEC08):
	[ Ditto - there was too much to write it all down,
	  although I'll bite the bullet and do it if the
	  other provided information is insufficient.]
panic: Bus error
Stopped at     _Debugger+0x6:     unlk a6
db> trace
_Debugger(0,dec40,9362c,93310,4c4b40) + 6
db> continue
syncing disks... ncr5380_status: none?

After this, things sort of hung. Hitting the debuggerer switch brought me
back to a db> prompt, but I couldn't seemingly do anything, so I hit the
reboot switch.

Now, when I tried booting with my 1.3_ALPHA kernel and the 1.3_BETA
binaries, things went well. Everything seems to work. (I don't have space
to keep more than one set of tarfiles around, so I don't have 1.3_ALPHA
binaries any more. It's 1.3_BETA or nothing. :)

Also, note that I haven't tried a generic kernel. I need a couple changes
in my kernel, so generic won't suffice for me, although I'll try one if
it's deemed necessary. (Specifically, I need SLIP's MTU to be 1500, which
happens in my kernel config.) My kernel compile last night seemed to go
without a hitch.

Mail and uucp seem to be working, FWIW. I haven't updated /etc in ages, and
likely won't until 1.3 (final) is finished, but I don't think there's any
problem there, as my error seems to be happening before the kernel starts
doing anything with the rest of the world, as far as I can see.

Things are working, so my machine isn't disabled or anything, but I'm
guessing that this ought to be addressed somehow.

Here's my kernel config file, and a diff file showing the difference
between my config and the copy of the generic config I have. I assume that
the generic config file gets updated with my kernel source sups. If not,
the diff file probably won't be helpful.
