Hi All, I have an Intel 3945ABG in my Toshiba R600 laptop which fairly reliably panics a while after I associate it with a WPA AP. It will happily associate and pass packets for some time (10's of minutes) and then panic. I have managed to trigger it both times I've tried to associate with this particular AP (some sort of NetGear 802.11n capable unit). Plenty of details here: http://people.freebsd.org/~lstewart/misc/wpi_debug/core.txt http://people.freebsd.org/~lstewart/misc/wpi_debug/kgdb_output.txt My /etc/wpa_supplicant.conf: ########## ctrl_interface=/var/run/wpa_supplicant ctrl_interface_group=wheel network={ ssid="X" proto=WPA psk="Y" } ########## Suggestions most welcome. In particular, the comment above the KASSERT that is firing in frame 10 seems to indicate that some prodding at the logic in the michael_mic() function may be required. Cheers, Lawrence
