Hi Nethanel,

On my machine
cat /proc/sys/kernel/sysrq outputs 438.

I changed the following to 1 but it made no difference.

REISUB doesn't work when the system freezes.
echo 1 > /proc/sys/kernel/sysrq

Kernel does not reboot system automatically when the system freezes.
echo 1 > /proc/sys/kernel/panic

Thanks
