Detect Soft Lockups

Linux Kernel Configuration
└─>Detect Soft Lockups
In linux kernel since version 2.6.14 (release Date: 2005-10-27)  
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

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