Date: Mon, 07 Sep 2009 00:05:51 +0300 From: Maxim Levitsky <maximlevitsky@...il.com> To: linux-kernel <linux-kernel@...r.kernel.org> Cc: "linux-acpi@...r.kernel.org" <linux-acpi@...r.kernel.org> Subject: [BUG] partial and rare system freeze I have noticed that sometimes keyboard input would stop working, and system will refuse to do many things. I tried to ssh to this system, but again after a login I can't type a thing. Then I realized that I can run a program via ssh, so I did run the dmesg, and here important parts of it: [ 79.101221] ACPI Error (dswload-0790): [_T_0] Namespace lookup failure, AE_ALREADY_EXISTS [ 79.101232] ACPI Exception: AE_ALREADY_EXISTS, During name lookup/catalog 20090521 psloop-227 [ 79.101240] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.WMID.WMBA] (Node ffff88007f8400c0), AE_ALREADY_EXISTS [ 79.101254] ACPI: Marking method WMBA as Serialized because of AE_ALREADY_EXISTS error Is very likely due to acer-wmi module I use to control brightness.
