[Oops] SMP lockup; NMI-watchdog caught and decoded

[Frank Horowitz]

G'Day,

A NMI-watchdog captured Oops. 

FWIW, I was moving the mouse at the time of the freeze, and had just
been mucking around with getting lm-sensors configured.

Setup: Dual Xeon 2.4s (hyperthreading on) on i7505 chipset based
motherboard. Running the nvidia binary driver (from vanilla debian
nvidia-kernel-installer).

I'm happy to help remotely debug this...

ksymoops 2.4.9 on i686 2.6.5.  Options used
     -V (default)
     -k /proc/kallsyms (specified)
     -l /proc/modules (default)
     -o /lib/modules/2.6.5/ (default)
     -m /boot/System.map-2.6.5 (default)
 
Warning (read_ksyms): no kernel symbols in ksyms, is /proc/kallsyms a
valid ksyms file?
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
