From mboxrd@z Thu Jan 1 00:00:00 1970 From: Daniel Kuhn Subject: BTRFS crash during mount Date: Wed, 08 Feb 2012 23:19:46 +0100 Message-ID: <4F32F502.6070307@swissonline.ch> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed To: linux-btrfs@vger.kernel.org Return-path: List-ID: After a forced power turn-off the filesystem of my primary boot partition cannot be mounted anymore, btrfs crashes during the mount process. I'm using OpenSuse 12.1 but I've also tried mounting with a newer kernel 3.2.2 (systemrescue cd) and with a usb-converter connected to another PC without success. The kernel log seems pretty specific about the crash location, see below.
