    Some more info:

    This bug is 100% reproducible. During boot, as soon as the i8042 driver
    is loaded:

    serio: i8042 AUX port at 0x60,0x64 irq 12
    serio: i8042 KBD port at 0x60,0x64 irq 1
    input: AT Translated Set 2 keyboard on isa0060/serio0

    the keyboard freezes, with 'Num Lock' stuck on.

    The problem only occurs when CONFIG_PREEMPT_HARDIRQS=y. Works fine
    otherwise.

    /proc/interrupts:
