Solution
Revert to factory default and restore config from backup (or re-insert into cluster).
If that doesn't work, you have to hardware-boot it, format the boot device and reload the OS from TFTP. (These options are available from the first-interrupt menu that the firewall offers when powered on.)
If that doesn't work, you probably have a faulty drive and should RMA.
