From 0ace0135233f7a9c553eefd626384cdd2dd53e9e Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Fri, 30 Oct 2015 11:29:14 +0100 Subject: [PATCH] sandybridge: Disable parallel CPU initialization Disable the parallel CPU initialization for model_206ax, that is Sandy Bridge and Ivy Bridge processors. We never did it the way that Intel recommends and it became unreliable with the introduction of SMM_MODULES in commit a3e41c0 Migrate 206ax to SMM_MODULES. Tested by booting kontron/ktqm77 2.6k times into Linux user space. No issues so far.
