Subject: [PATCH 2/2] kernel-parameters.txt: Add new entry for i8042.noselftest
Date: Mon, 25 Jul 2016 14:20:19 -0300 [thread overview]
Message-ID: <1469467222-2382-4-git-send-email-marcos.souza.org@gmail.com> (raw)
In-Reply-To: <1469467222-2382-1-git-send-email-marcos.souza.org@gmail.com>
This new parameter makes i8042 controller to skip selftest. It's
useful to test some problems in touchpads that stop to work after
a suspend/resume cycle.
