panic: trap
Stopped in pid 3.1 (scsibus1) at        netbsd:cpu_Debugger+0x14:       or

And now for the backtrace:

Another thing you can get is the failing instruction (Using the pc value from the trap information above):

db> x/i 0xfffffc00004ea978

  Maybe even several instructions (to help me figure out where in the code
the trap occurred):

db> x/i 0xfffffc00004ea978,20
