I cannot scientifically say yes, but by memory I'd say that it does after a full unload/reload of ipw2100 module. I will of course test this if it happens again.

Meanwhile I got the crash also with 2.6.32 (attached), so it's definitively a not yet fixed bug and not something due to my custom patches.

Triggering conditions are basically "hammering" the device to change APs without any ipw2100 module reload in the process.

P.S. I think the acpid event can be ignored because I disconnected an USB device at that time (totally unrelated).

Thanks,
