I'm getting this panic sometimes when I reboot:

syncing disks... 2 2 dome
Rebooting...
trap: TLB miss (load or instr. fetch) in kernel mode
status=0xf003, cause=0xc08, epc=0x8117100c, vaddr=0x3e00008
pid=0 cmd=swapper usp=0x0 ksp=0xc29d3d70
Stopped in pid 0.1 (swapper) at 0x8117100c:           lw           t6,0(t7)
db>

At that point I can't type anything into the debugger, I'm hung hard.
Gotta press the reset button.

I haven't found much that is similar, but I'm not sure I'm searching correctly.
