Subject2.4.21-pre4-ac4 oops
From
I got this oops in XFree86 when switching desktops within KDE....


ksymoops 2.4.5 on i586 2.4.21-pre4-ac4. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.21-pre4-ac4/ (default)
-m /boot/System.map-2.4.21-pre4-ac4 (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.
