Date: Wed, 27 May 2009 01:54:26 +0200 From: Andi Kleen <andi@...stfloor.org> To: linux-kernel@...r.kernel.org, hpa@...or.com, x86@...nel.org Cc: Andi Kleen <ak@...ux.intel.com> Subject: [PATCH 24/31] x86: MCE: Don't print backtrace on machine checks with DEBUG_BUGVERBOSE From: Andi Kleen <ak@...ux.intel.com> CONFIG_DEBUG_BUGVERBOSE prints backtraces on panics, but we don't want that on machine checks because these are not kernel bugs. So disable it here.
