Subject2.2.10-pre4: still oops rmmod-ing ide-mod
Date
In 2.2.10-pre4 "rmmod ide-mod" still causes Oops (intoduced in 2.2.9?)
After that, IDE is not usable, and "lsmod" does not work. Follows
"ksymoops" log:
===========
Options used: -V (default)
-o /lib/modules/2.2.10/ (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-m /usr/src/linux/System.map (default)
-c 1 (default)

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.
