To turn it on, you can set the
kernel.panic kernel parameter.
For a running system:
# echo 10 >/proc/sys/kernel/panic
Here, 10 is the number of seconds before the kernel reboots. 0 means the feature is disabled.
To make the configuration persistent, you have 2 choices:
- add the kernel parameter
panic=10to your bootloader (grub or grub2).
kernel.panic = 10to /etc/sysctl.conf by typing in the terminal sudo nano /etc/sysctl.conf.
After you enabled the auto reboot after kernel panic, you may need to check the uptime and logs or create a
@reboot cron jobs to send emails or use some other mechanisms to know that there was a auto reboot caused by a kernel panic.
