Kernel panic timeout
Medium Severity
Set the timeout value (in seconds) until a reboot occurs when the kernel panics. A timeout of 0 configures the system to wait forever. With a timeout value greater than 0, the system will wait the specified amount of seconds before rebooting. While a timeout value less than 0 makes the system reboot immediately. The configuration that was used to build kernel is available at
/boot/config-*
. To check the configuration value for
CONFIG_PANIC_TIMEOUT
, run the following command:
grep CONFIG_PANIC_TIMEOUT /boot/config-*
For each kernel installed, a line with value "
" should be returned.
