That looks kind of similar to one I just got (on r295122 , during a
lot of ZFS traffic) : https://goo.gl/photos/UkPV2BVi27Yucdgn7

Buildworld and installworld doesn't seem to be enough to trigger it
for me - I'm upgrading it to whatever CURRENT was at an hour ago now.
I couldn't get any further contact with the debugger (plugging in a
USB keyboard post-panic didn't do much), but I left it connected now,
and I should be able to set up a dump device and/or serial debugging.

(The GSS kernel config I'm using is just amd64 GENERIC + options KGSSAPI .)
