I have a btrfs filesystem with three subvolumes. One of them (named arch64) has 64 bit linux, one (arch32) has 32 bit linux, and the third (files) has various files. After an unsuccessful tuxonice resume, the arch64 subvolume will no longer boot. It shows this bug: VFS: Mounted root (btrfs filesystem) readonly on device 0:13. Freeing unused kernel memory: 480k freed BFS CPU scheduler v0.315 by Con Kolivas.
