Subject: [ath9k-devel] modprobe ath9k == BUG: unable to handle kernel NULL pointer dereference at 000001dc
Date: Thu, 22 Jan 2009 14:19:00 -0500 [thread overview]
Message-ID: <4978C6A4.4050709@cheek.com> (raw)
In-Reply-To: <49779F1D.2090800@cheek.com>
I just got a repro of this on 2.6.27.12 with compat-wireless
2009-01-19. i'm going back to 2.6.27.11 with compat-wireless 2008-12-31
to see if it is more stable (I never got the bug on that one).
here are the config_debug options i had on for this last strace. please
let me know what other options you would like me to turn on so i can
make the trace more useful.
thanks!
