Hm, weird bug.
I can't reproduce this on i386 or PPC.
Could it be a bug in the lockdep code?

No - it picks up with regular log messages at that point.

It could be. I'll send it on to LKML. Perhaps one of the experts
there can tell us. It doesn't seem to cause any trouble, but I get
one of these when bcm43xx starts.
Are you running WPA? The message seems to occur just after
wpa_supplicant finishes the connection and sets the security flags.

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
kernel: bcm43xx: set security called, .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

is there anything more in the backtrace? Right now the most crucial 2 to
4 lines are missing, eg the bits just below this ;)
