Using vanilla wireless-2.6 from Linville's tree as updated Aug 15, I
get a single warning generated by the statement
         if (DEBUG_LOCKS_WARN_ON(!irqs_disabled()))
in kernel/lockdep.c. This warning only occurs when my wireless
interface is inserted, bcm43xx-softmac is activated, and it
authenticates and associates. I'm running WPA-PSK TKIP using
wpa_supplicant, and the message seems to be output just after
the supplicant finishes making the connection.

kernel: SoftMAC: sent association request!
kernel: SoftMAC: associated!
kernel: bcm43xx: set security called, .active_key = 0, .level = 2,
.enabled = 1, .encrypt = 1

I'm at a loss here. Can anyone explain how to interpret this dump? I
think I see a general protection fault, but what to do from there is a
mystery.

Thanks,

Larry
