From d5acaaf8451d727107b53882c9d3bae4482fe0b8 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Tue, 17 Dec 2013 15:35:51 -0800 Subject: lynxpoint: Don't enable SMI handling of TCO We have no good reason to be handling the TCO timeout as an SMI since we aren't doing anything special with it and clearing the status in the handler prevents the reboot from actually happening.
