It's trying to jump to a restart location in the boot rom.
It fetches a bad instruction that attempts to execute
as a floating point instruction.

This program counter is a typical warm restart boot
rom location.  Change the kernel reboot code to jump
to the proper place in your boot rom or force a restart
in some way.
