Just got this oops in 2.4.5-ac2. Can't reproduce it as of yet; if I
find a way, I'll give notice.

ksymoops 2.3.4 on i586 2.4.5-ac2. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.5-ac2/ (default) -m /boot/System.map-2.4.5-ac2 (default)

Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options.

Warning (compare_maps): ksyms_base symbol __io_virt_debug_R__ver___io_virt_debug not found in System.map.
