CONFIG_DETECT_SOFTLOCKUP: Detect Soft Lockups

General informations

The Linux kernel configuration item CONFIG_DETECT_SOFTLOCKUP:

Help text

Say Y here to enable the kernel to detect "soft lockups", which are bugs that cause the kernel to loop in kernel mode for more than 60 seconds, without giving other tasks a chance to run.

When a soft-lockup is detected, the kernel will print the current stack trace (which you should report), but the system will stay locked up. This feature has negligible overhead.

(Note that "hard lockups" are separate type of bugs that can be detected via the NMI-watchdog, on platforms that support it.)
