not sure what this is, but while at a convention
I was trying to access the internet and(below is
full dmesg) this showed up.

After receiving this, I sat and tried to re-create
my steps to reproduce but had no luck(was even going
todo a bisect n the spot if I could re-create).

OK this stuff is hard to reproduce it seems.. you have an Atheros
AR5418 MAC/BB Rev:2 AR5133 RF Rev:81, what kconfig option do you use
to get the poison stuff? I am just surprised we haven't seen it
ourselves yet. Let me make sure all of us get this kconfig option
enabled.

     Luis

CONFIG_ATH_COMMON=m
# CONFIG_ATH_DEBUG is not set
CONFIG_ATH5K=m
# CONFIG_ATH5K_DEBUG is not set
CONFIG_ATH9K_HW=m
CONFIG_ATH9K_COMMON=m
CONFIG_ATH9K=m
# CONFIG_ATH9K_DEBUGFS is not set

if you need my .config let me know.
(I can try again reproducing, but man
just doesn't easily fire off).

Oh I mean the config options to enable the poison rant.

     Luis

shoot.. not sure how to grep for the right info
in the .config for you, heres what grepping for COFIG_DEBUG
looks like:
CONFIG_DEBUG_FS=y
CONFIG_DEBUG_KERNEL=y
CONFIG_DEBUG_RT_MUTEXES=y
CONFIG_DEBUG_PI_LIST=y
CONFIG_DEBUG_SPINLOCK=y
CONFIG_DEBUG_MUTEXES=y
CONFIG_DEBUG_BUGVERBOSE=y
CONFIG_DEBUG_MEMORY_INIT=y
CONFIG_DEBUG_STACKOVERFLOW=y

oh, this reminds me of a similar report we had for ath5k:

https://bugzilla.kernel.org/show_bug.cgi?id=15861

the subject on this mailing list was "ath5k misbehaving affecting other kernel
parts unrelated?"

bruno


Could be.. From what I remember
all I was doing was switching from
one wireless network to another
(then opening firefox to sign my life away).

Were you using network-manager? Or the supplicant manually?

   Luis


I've got wicd(1.5.9) manager
running over here.
