Nothing special with this box. SMP no modules, Squid proxy and
running VNC/Pan at the time. Using kernel version of reiserfs on
filesystems other than root.
Be glad to offer any other info if needed.

I also failed to mention that I use devfs.

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.

Another NMI oops?
You've deadlocked over my old friend console_lock. I can't
see _why_ though. Was this with the same setup, using the
serial console? If so then probably the other CPU was
stuck in the serial console driver, holding console_lock.
