DDB is enabled (I can enter the debugger from the console) and ddb.onpanic
was set to 1. Thats why I am mystified as to how to debug it. Its
rebooting without a panic message / core dump (savecore doesn't come up
with anything). It doesn't even try to flush the disks before rebooting -
the screen just flickers and the boot sequence begins.
