[net.unix-wizards] 4.2bsd Vax 750 disk problems

I don't recall a discussion of the following problem we are
experiencing with even the generic version of 4.2bsd on our 750.
I'd appreciate some help or a pointer to previous discussions/fixes.

Our 750 is configured with 2 rk07s, one ra81, and a tu78.  We have
4.2 running with the root on an rk07 and everything else on the ra81.
Every time we spin up/down the second rk07 to exchange cartridges,
we get a "lost hk interrupt" and a panic trap.

Could this be due to the distributed uda driver (we have not installed
any fixes yet) or is the rk07 support flakey?

Thanks,
