FWIW, I ran into this problem in July.  My BT747 (EISA) was causing this
panic on a 12GB CCD.  I didn't have it all of the time though, and the
machine has been fairly stable.  I'll try the test program also.

I have these Buslogic (and Bustek) controllers:
	BT956C	pci  (fairly new)
	BT747	eisa (fairly new)
	BT742A	eisa (fairly old)
	BT542	isa  (really old, might be a 542A, have to look)

I'll be happy to help test, or just provide a serial console to a box
with any of these.

I can definitely help with the controllers mentioned above.  I have
only seen the problem on my BT747 though.
Let me know via private email if you want serial console access.
