Possible uda50 driver problem

HELP!

We are having problems with a VAX 11/750 running 4.2BSD. It all started
when the air-flow sensor got bunged up with a ball of fluff, thus
precipitating several removals of power from the system. Now, it panic
traps with Memory Protection violations (trap type 9) from the uda50
driver in routine 'udrsp' at infrequent intervals, causing considerable
consternation amoung the 15-odd users!

Now, it is probably a hardware fault, but it could be a problem with
the uda50 driver. I will probably need to get stuck in with reams of
assembler/C listings if the engineer can't fix it, but to save time,
does anyone out there know of any problems with the May 1985 version of
the RIACS driver containing Mike Muuss' unit/type detection code, and
the bad block replcement software?

Many thanks in anticipation
