From bfe8e5186ea9916634d31182ec0437f6175e7724 Mon Sep 17 00:00:00 2001 From: Sven Schnelle Date: Tue, 14 Jun 2011 20:55:54 +0200 Subject: SMM: don't overwrite SMM memory on resume Overwriting the SMM Area on resume leaves us with all variables cleared out, i.e., the GNVS pointer is no longer available, which makes SMIF function calls impossible.
