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.
