It always seems to get through the fsck, but after the filesystems are
mounted read/write everything breaks up.

The same kernel works when booted in an ISA system with IDE disks, so
this is PCI/NCR/SCSI related.

I think someone else had the same problem, but I could not find a reference.

How-To-Repeat: 
Reboot with ftp://clinet.fi/pub/FreeBSD/crashdumps/kernel.broken.3.
It might be that repeating this requires oddities like having two NCR
SCSI controllers.

I belive this is the same bug that was fixed this morning, a  
sign-extension in the ufs code.
