-- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1413008 Title: Kernel BUG shortly after mounting btrfs filesystem Status in linux package in Ubuntu: Confirmed Bug description: This bug happens entirely reproducibly after mounting a multi-disc btrfs filesystem I have. It is reproducible on the current Vivid 3.18 kernel and the mainline 3.19-rc5 build; I recall this bug also happening on Utopic's 3.16 kernel, but don't have logs. All processes that touch the filesystem then hang indefinitely in the kernel.
