Subject: [ath9k-devel] modprobe ath9k == BUG: unable to handle kernel NULL pointer dereference at 000001dc
Date: Wed, 21 Jan 2009 01:14:06 -0500 [thread overview]
Message-ID: <4976BD2E.3070807@cheek.com> (raw)
Not sure how reproduceable this is as it's the only one i have seen
yet. but i just got it with 2.6.28.1 and compat-wireless-2009-01-19.
the kernel didn't oops but ifconfig did hang. I could login on another
VC and get a responsive system, but trying to ifconfig the interface
down did not work. i ended up hard-resetting.
