Yes, this is very much reproduceable. If you look at the dmesg you will also see the previous reboot for the same reason but with a different device - a WLAN stick that also includes some mass storage for the windows driver and probably another for the mini-sd or whatever card fits in there.. The Pendrive I then used is a 64MB (yes, megabytes) so from that you can probably guess how ancient that thing is so it should not have any new and fancy options aka quirks ;). What I haven't tried yet is simply loading the module while no device is attached. I'll try that when I have the new kernel booted. It will take some time though since this is a 500MHz Geode.. I think I also saw a few other bugreports related to this issue maybe someone else already included a backtrace. Thanks for looking into this, Alex.
