I've reported this problem on my IIvx, as have other IIvx users. the
problem is indeed self-repairing, but very syslog-cluttering. the problem
seems to have been evident since GENERIC #47, but it've only used that and
GENERIC#56. i'd rather not use SBC if i don't have to. i don't think it
has anything to do with the drive, and whether it likes ncr or sbc, just
that the kernel isn't doing something right with ncrscsi on some machines 
- i hope this doesn't cause errors in future kernels to the extent that we
are not able to use ncrscsi.  I feel this way because ncr has always
worked on my machine, whereas sbc has had a reputation to hang on
boot (SBC#55 booted successfully, however). i wonder if this was a known
bug that's been fixed...
