I'm sure there are ways to read out a CPU Hang and reset if that happens, if necessary via external hardware^(I'm guessing)^(I don't actually know)

- fooker 9y agoSure, just have the 'os' ping the external device in N second intervals. Without a ping, reset through a jumper.
- flopunctro 9y agoSome enterprise-grade server platforms already have this functionality, it's called a "watchdog". Linux supports this since (at least) 2.4. I've been using this with HP ProLiant servers and (for me, at least) it has always worked as intended. For more info, search "linux watchdog timer".

- wongarsu 9y agoIt would also be fairly simple to build for any computer using just an arduino or a raspberry pi. The computer could send a periodic signal over the serial port, if the arduino doesn't receive a signal for some time it shorts the mainboard's reset pin, causing a reboot.
