Subject: [ath9k-devel] BUG in ath9k_tx
Date: Tue, 14 Sep 2010 14:10:04 -0700 [thread overview]
Message-ID: <4C8FE4AC.3040107@candelatech.com> (raw)
I am running 2.6.36-rc4-wl+, with Johannes's sta_info_get_bss patch,
my ath9k rxfilter patch, and Felix's bssid-mask patch.
I had created two un-encrypted STA interfaces. I was messing with another
machine, trying to get a sniffer working when this happened.
I saw this a few days ago as well, but didn't get a chance to get a good
stacktrace.
