I'm getting a kernel oops on the intel woodruf P4 motherboard under 
2.4.22pre10.  This config worked fine under 2.4.21.  The output of 
ksymoops is attached, and the raw oops is attached.

ksymoops 2.4.4 on i686 2.4.20-8smp.  Options used
     -V (default)
     -K (specified)
     -L (specified)
     -O (specified)
     -m /boot/System.map-2.4.22-pre10 (specified)
