Help text

Say Y here to enable the kernel to panic on "soft lockups", which are bugs that cause the kernel to loop in kernel mode for more than 20 seconds (configurable using the watchdog_thresh sysctl), without giving other tasks a chance to run.

The panic can be used in combination with panic_timeout, to cause the system to reboot automatically after a lockup has been detected. This feature is useful for high-availability systems that have uptime guarantees and where a lockup must be resolved ASAP.

Say N if unsure.
