Oops in 2.4.1

[MATSUSHIMA Akihiro]

Hello.

When I boot my system (Vine Linux 2.1), my system crashes.
This oops is reproducable with the kernels: 2.4.0-ac11,
2.4.0-ac12 and 2.4.1(probably all >= 2.4.0-ac).
The decoded oops follows:

---------
ksymoops 2.3.7 on i586 2.4.1.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.1/ (default)
     -m /usr/src/linux/System.map (default)
