Can you set up a serial console on this system? If so, enable these
kernel options:
options DDB
options WITNESS
options INVARIANTS
options INVARIANTS_SUPPORT
options BREAK_TO_DEBUGGER
Boot through the serial console then trigger the bug and send a break from
serial. If you drop into ddb, then its a Giant deadlock.
If you can get that, then do 'show locks' from ddb to get a list of
potential culprits, and 'tr' for what its stuck doing.
The kernel handbook section on kernel debugging will be a useful read.
