From 846b4941fee842bc359fa2b611cf0c3fc4f158b2 Mon Sep 17 00:00:00 2001 From: Raul E Rangel Date: Tue, 12 Jun 2018 10:43:09 -0600 Subject: stoneyridge: Increase SMM stack size to 2K GSMI Set Event Log is taking more than 1K in stack. This causes the stack to overflow into the adjacent stack. This has the side effect of causing any CPU waiting for the SMI handler to complete to crash when the lock is unlocked because the return pointer has been smashed. BUG=b:80539294 TEST=built on grunt and tested by running `halt` from the OS.
