kdb and recent Redhat kernels flash the keyboard leds during a panic to
tell you that the kernel is dead.  If you are sitting in X with no
console visible it is often the only indication you get that a kernel
has died.

To disable this feature, in arch/i386/kdb/kdba_io.c change

#define KDB_BLINK_LED 1

to

#undef KDB_BLINK_LED
