On the console i ran 'top', but it wouldn't start,
giving:

load: 0.00  cmd: top 4282 [sysctl lock] 0.00u 0.00s 0% 180k

as the status. I can't ^C it, can't ssh in.
can still ping the device.

It was doing a backgound fsck from an earlier hang.

i have called panic from db, not sure if the core will
work properly or not.

Dropping to db, shows:
