Reboot the system automatically when the kernel hangs

[coiby]

For issues like RHEL-145168, RHEL-130927 and etc, the kdump kernel can hang. So it's ideal to reboot the system so the bisecting can continue.

Currently, users need to manually reboot the system or using a script like follows,

host=$1
MAX_WAIT_TIME_S=200
SLEEP_S=5

while :; do
	until ssh -o ConnectTimeout=3 -o ChannelTimeout=session=2s "$host" exit 2>/dev/null; do
		if [[ $elapse_time -gt $MAX_WAIT_TIME_S ]]; then
			bkr system-power "$host"
			elapse_time=0
		fi
		elapse_time=$((elapse_time + SLEEP_S))
		sleep "$SLEEP_S"
	done

	elapse_time=0
	sleep "$SLEEP_S"
done
