Say Y here to enable the kernel to detect interrupt storm
during "soft lockups".
"soft lockups" can be caused by a variety of reasons. If one is
caused by an interrupt storm, then the storming interrupts will not
be on the callstack. To detect this case, it is necessary to report
the CPU stats and the interrupt counts during the "soft lockups".
