I need to know: how do not automatically restart GNU/Linux after a critical system failure (kernel panic). For some reason the pc is rebooted, actually throws the error screen Reboot just moments before, but I can't to read it before you reboot. I tried using:

echo 0 > /proc/sys/kernel/panic

sysctl -p

and I find that the value is stored with

cat /proc/sys/kernel/panic

but still does not work, does anyone know another way to indicate that no restart linux after a failure?

On NetBSD we add the following line to /etc/sysctl.conf to make it reboot automatically on kernel panic:

  • ddb.onpanic=0

Perhaps that setting is what you need on Linux (but with a different value to make it not reboot)? I don't know if it's the same though.
