(In reply to Robin Randhawa from comment #6)

That certainly looks like the same issue. I'm working with the driver developer
on this issue and we have reproduced it on my system. I've sent some debugging
info, but may need to run an specially-instrumented version of the driver to
track down where the fault is being triggered.

If you need this working (with possibly VERY reduced performance), you can add:

hw.nvme.per_cpu_io_queues=0

to your /boot/loader.conf file. Note that this is a workaround, not a fix.
