In case it still matters to someone, I got this same error on an external USB 2 GB drive with the stock 12.04 kernel (3.2.0-27):
kernel BUG at /build/buildd/linux-3.2.0/fs/btrfs/extent-tree.c:2287! I installed kernel 3.4.7 as suggested above and it did, indeed, fix the issue. The drive mounted read-only until I ran "btrfsck --repair" (from btrfs-tools_0.19+20120328-7_amd64.deb), but after that it seemed ok, and I never got the 'kernel BUG' screen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/970402 Title: kernel BUG at /build/buildd/linux-3.2.0/fs/btrfs/extent-tree.c:2287!
