Hello, i have a AVM wlan usb stick for testing, usb id 057C:6201. I try the avm linux driver with kernel 2.6.23.12-2. Build and modprobe is ok, inserting the stick gaves after a long period of waiting the wlan0 device. iwpriv wlan0 work, iwconfig stopped with a segfault and a oops. I'm not a kernel guru or developer, but maybe could someone say (without a full dump or so) what the reason for this trap? (Yeah, i know the short answer: tainted by fwlanusb ;-) If @tpowa reads this: if see strcopy in trap, could this be something similar we have had with avm fritz card and the objcopy-Patches? Thank you for having a look at this! Legend: 14:33:10 after modprobe and wlan0 ready 14:33:45 iwconfig ------------- Dec 22 14:33:10 tux1 fwlanusb: Config manager successully created and started.
