#1998: Kernel panic from madwifi after repeated disassociations
-------------------------------+--------------------------------------------
Reporter: [EMAIL PROTECTED] | Type: defect
Status: new | Priority: minor
Component: madwifi: driver | Version: trunk
Keywords: | Patch_attached: 0
-------------------------------+--------------------------------------------
I have an access point that is using an Atheros AR5006X, and a laptop
using an Atheros AR5212 card. Both are running madwifi from SVN - 3717 on
the AP, and 3721 on the laptop. The network uses WPA2-Enterprise, with
hostapd on the AP and wpa_supplicant on the laptop.
After being associated to the AP for a while, my laptop gets disassociated
for no apparent reason. After that, every association is immediately
followed by a disassociation. Unloading the modules and restarting the
interface on the laptop has no effect - only rebooting seems to help, and
that is only temporary.
If I allow the association/disassociation loop to run long enough, the
kernel panics. It usually only takes a minute or two for this to occur.
My wife's laptop is using an iwl3945 card with wpa_supplicant, and does
not exhibit this problem at all.
This situation is highly reproducible - I have experienced as many as 6
hard kernel panics within the space of an hour.
I am attaching the most complete kernel dump I have obtained so far. It
is missing some information, so please let me know if what is present is
insufficient.
