If the crash was bad enough to freeze the kernel before it could
trigger the reboot, there is nothing the software can do.

You need a hardware watchdog. If your motherboard has one, just install
and enable the corresponding daemon, and check it works by SIGSTOPing
it.

If your motherboard does not have one, you can probably DIY one from a
RPi or an Arduino.
