Subject: [REGRESSION][v3.5] iwlwifi: include rssi as part of decision making for reduce txpower
Date: Fri, 03 Aug 2012 12:24:09 -0400 [thread overview]
Message-ID: <501BFB29.7010801@canonical.com> (raw)
Hello,
A bug[0] was reported against Ubuntu that reports a kernel panic when
using the hotkey to disable then re-enable wifi on a Dell XPS 14z. A
kernel bisect was performed, which indicated the following commit as the
source of the regression:
