Date: Fri, 17 Sep 2010 14:56:25 +0200 From: Conny Seidel <conny.seidel@....com> To: Huang Ying <ying.huang@...el.com> CC: Andi Kleen <ak@...ux.intel.com>, Len Brown <len.brown@...el.com>, LKML <linux-kernel@...r.kernel.org>, "borislav.petkov@" <amd.com.borislav.petkov@....com> Subject: 7ad6e9435596f692ff65f399da12816c94960185 breaks AMD f10h. Hi, Kernel v2.6.36-rc4-134-g03a7ab0 breaks with the OOPS below. Reverting the commitid in the subject fixes the issue. This is because APEI is selected by default on X86 (X86 && ACPI), maybe a vendor check in the hest_init() might make sense. Kernel config is attached.
