I'm not sure if it's interesting or not.
On ASUS WL-500gP (MIPS platform, with OpenWRT patches), running 2.6.29.3
kernel, I'm getting an Oops (see below) when I remove the ipw2100 module
and modprobe it again.
Let me know if I should decode the Oops etc., or if has perhaps something to do with the board
not fully supported by the upstream kernel, and just leave it.
Please decode the oops... :-)
Umm...
# cat oops.txt | ksymoops
ksymoops 2.4.11 on mips 2.6.29.3. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.6.29.3/ (default)
-m /boot/System.map-2.6.29.3 (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.
Error (regular_file): read_ksyms stat /proc/ksyms failed
ksymoops: No such file or directory
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
