In other kernels I've gotten a 'scsi timeout error'. But I've had this
when I was in 'single user mode' so swapping hasn't been enabled. And
I saw it just as I was moving to multi-mode on one occasion. (It's
done this a couple of times).

Could the 'ADB' driver effect the system timing/interupts such
that the disk driver could complete a operation, and for some
reason 'forget' that and attempt to mark the buffer as done again,
which is my unexamined guess as to what 'biodone' means.

My config is:

Mac II
Toby Frame Buffer.

At the moment no other cards are operable.

The next opportunity to check this out will be thursday night...
So maybe I'll have a better matrix of failure to give.
