Hello,
this time I caught a panic with a debuging kernel under 11.1-BETA1,
which again occured after shuting down a VM which had ppt in use:

This machine is usually rock solid, but shows most strange errors each
time I utilize "passthru" with bhyve.
Besides runngin a debug kernel, I don't know how to help tracking this down.
I can imagine that above quoted PR and the unexplainable »lib/libc.so.7:
Undefined symbol "xdr_accepted_reply"« error all have the same
undiscovered cause, which shows up as soon as byhve and passtrhu are
involved.
Please, can anybody of the xperts add a comment?
Thanks,
-harry
