I'm using a bt747s since Oct. '93 together with NetBSD-current. No problem
at all, until yesterday (I got a brand new bt747s for my second NetBSD
system). With this new bt747s I got a similar message.

I verified both bt747s and the only difference I found: 
they have different firmware and bios revisions

firmware 3.31, bios 4.50: everything works for me since Oct. '93
firmware 3.37, bios 4.70: NetBSD-current doesn't work for me

Using the old firmware and bios EPROMS together with the new bt747s
fixed the problem for me.
