vanishing ioctl handler debugging We've had several reoprts of the CPU jumping to 0x00000000 is do_ioctl(). I assume that there's a race and someone is zeroing out the ioctl handler while this CPU waits for the lock_kernel(). The patch adds code to detect this, then emits stuff which will hopefuly lead us to the culprit.
