The hardware has run 2.3x SMP kernels successfully for over a year.
I tried running the 2.4.4 kernel that is crashing with the 'nosmp' option, and it booted ok.
The ksymoops output:
ksymoops 2.4.0 on i686 2.4.4. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.4/ (default) -m System.map (specified)
