I've got a panic when I tried to reboot the machine after running
some stress tests.  I'm not sure if this one is easily reproducible, but
here's the last message anyway:

boot() called on cpu#1
Switching to cpu #0 for shutdown

The kernel dump is on my leaf account as ~y0netan1/crash/{kernel,vmcore}.8 .
