I've just tried upgrading a Pentium box with an Adaptec AHA-2940 (Fast,
not Ultra SCSI version, BIOS 1.23) which is happily running NetBSD
1.4.1, to 1.5, and the 1.5 installation kernel panics with:

ahc1: brkadrint, Sequencer Parity Error at seqaddr=0x13c

which is kinda disappointing. ahc probes it as an aic7870 chip. Couldn't
see any PRs relating to this - anybody seen this before? Any ideas?

Cheers,
