Kurt, could you please create a PR and point me to the PR number so RE

The PR is: 201245

I put the short version of the panic backtrace in the bug, and
attached the full core.txt.0 file to the bug as well, as it
contains the detailed backtrace.

I got all excited and decided to give it a try on my dual-cpu
V240 as well. I was able to get it installed, but it panics
when booting off the mirrored ZFS drives. (Note: I have no
reason to believe this is ZFS related.)

Now the thing that amazes me is that this happened
the first three times after I did the install, and
on the fourth boot, it didn't panic. And it was
able to 'savecore' the crashdump.
Here's the stacktrace from the core.txt.0 file:
