Subject: [PATCH] Input: i8042 - introduce noaux dmi quirk for MSI AE2220
Date: Tue, 23 Mar 2010 15:50:24 +0100	[thread overview]
Message-ID: <20100323155025.3a541cbd@destiny.ordissimo> (raw)
In-Reply-To: <20100322144514.45391412@destiny.ordissimo>


This computer does no have an external PS2 port, and booting without
i8042.noaux induces a 10 second boot delay, until the AUX port detection
timeouts.

Hi,

This patch is against 2.6.34-rc2 and has been tested with kernel 2.6.33.1

Regards,

Anisse
