Say Y here to enable the kernel to act as a watchdog to detect soft lockups.

Softlockups are bugs that cause the kernel to loop in kernel mode for more than 20 seconds, without giving other tasks a chance to run. The current stack trace is displayed upon detection and the system will stay locked up.
