Would I be correct in assuming that you're using a serial
console, and that the oops was caused by the NMI watchdog?

It seems that this is _bound_ to happen - we're busy
waiting on the UART with interrupts disabled....

Some fixes which come to mind are:

1: the serial console code tells the NMI oopser that it knows what
it's doing.

2: the serial console code aborts the write if it doesn't make any
progress for 1/10th of a second.

3: Boot the kernel with the `nmi_watchdog=0' LILO option if you're
using an unreliable serial console.
