Message-Id: <20090407150748.401C71D046D@basil.firstfloor.org> Date: Tue, 7 Apr 2009 17:07:48 +0200 (CEST) From: Andi Kleen <andi@...stfloor.org> To: hpa@...or.com, linux-kernel@...r.kernel.org, mingo@...e.hu, tglx@...utronix.de Subject: [PATCH] [7/28] x86: MCE: Log corrected errors when panicing Impact: bugfix Normally the machine check handler ignores corrected errors and leaves them to machine_check_poll(). But when panicing mcp won't run, so log all errors. Note: this can still miss some cases until the "early no way out" patch later is applied too.
