I just got a new Conner 1080S for my birthday.  I installed it as sd1 and
installed 950412-SNAP on it.  I have a generic NCR810 card and a digital
ethernet card which so far have been sharing the PCI bus okay.  However,
while the machine is coming up, I get the following messages:

assertion "cp == np->header.cp" failed: file "../../pci/ncr.c", line 5235
assertion "cp" failed: file "../../pci/ncr.c", line 5236

The probe looks more or less normal:

50K/sec, I could do NFS over my ISDN line and be faster =)

Anyone have any suggestions?
