I thought that our 4.2bsd was fixed when we got it, because we looked at
the source code and it was already in there.  I looked and it is fixed.
Our VAX used to tbuf parity fault lots of times with 4.1bsd.  We added
the DEC unix patch and everything was fine.

The file is /sys/vax/machdep.c versions 6.1 (83/08/20) or 6.2 (83/10/02).
In version 6.2 the code is at line 811.

If you are still having system crashes because of tbuf parity faults,
check your source (if you have it) to make sure you have the latest
version.  If not, get it from someone so that you can recompile the kernal.
