Classification: openSUSE Product: openSUSE 12.1 Version: Final Platform: x86-64 OS/Version: SuSE Other Status: NEW Severity: Normal Priority: P5 - None Component: Other AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: steve@bradfield.org QAContact: qa@suse.de Found By: --- Blocker: --- Created an attachment (id=471281) --> (http://bugzilla.novell.com/attachment.cgi?id=471281) Log output from attempting to map from rescue dvd User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:9.0.1) Gecko/20100101 Firefox/9.0.1 This morning, my pc was fine. I modified a spreadsheet and saved. About 15 minutes later, I came back to wake it from screensaver and it would not respond at all. After several minutes, I restarted the system and now it will not load the /root partition. I booted from the rescue cd and tried to run fsck on the partitions, but nothing is reported. I tried mounting various partitions and all were successful with the exception of my root partition. When I try to mount that, it gives me a message "invalid opcode: 0000 [#1] SMP" and about 4 lines after that, but the mount fails. If I try again, the command line becomes unresponsive and I cannot break out. I was able to resolve the issue using the btrfs utility "btrfs-zero-log" Reproducible: Always Steps to Reproduce: 1. Reboot system 2. Initialization fails when it cannot load root file system 3. Repeat Alternatively, trying to map the partition from the rescue DVD produces same issue Actual Results: When I try to mount that, it gives me a message "invalid opcode: 0000 [#1] SMP" and about 4 lines after that, but the mount fails. If I try again, the command line becomes unresponsive and I cannot break out. Expected Results: Proper boot, mount root and load KDE Jan 13 18:35:33 Rescue kernel: [ 104.657253] ------------[ cut here ]------------ Jan 13 18:35:33 Rescue kernel: [ 104.657299] WARNING: at /home/abuild/rpmbuild/BUILD/kernel-default-3.1.0/linux-3.1/fs/btrfs/tree-log.c:1729 walk_down_log_tree+0x15a/0x3e0 [btrfs]() Jan 13 18:35:33 Rescue kernel: [ 104.657307] Hardware name: System Product Name Jan 13 18:35:33 Rescue kernel: [ 104.657311] Modules linked in: btrfs zlib_deflate nls_utf8 ppa arc4 ecb powernow_k8 mperf fan thermal nfs nfs_acl lockd fscache auth_rpcgss sunrpc nls_iso8859_1 nls_cp437 af_packet st usbhid usb_storage uas radeon ata_generic parport_pc ohci_hcd parport ttm drm_kms_helper button drm ehci_hcd wmi pata_atiixp xhci_hcd i2c_algo_bit ssb mmc_core usbcore sr_mod cdrom pcmcia pcmcia_core sg processor r8169 thermal_sys edd squashfs loop Jan 13 18:35:33 Rescue kernel: [ 104.657389] Pid: 2751, comm: mount Not tainted 3.1.0-1.2-default #1 Jan 13 18:35:33 Rescue kernel: [ 104.657394] Call Trace: Jan 13 18:35:33 Rescue kernel: [ 104.657421] [<ffffffff810042fa>] dump_trace+0x9a/0x270 Jan 13 18:35:33 Rescue kernel: [ 104.657435] [<ffffffff81523edb>] dump_stack+0x69/0x6f Jan 13 18:35:33 Rescue kernel: [ 104.657449] [<ffffffff81051eab>] warn_slowpath_common+0x7b/0xc0 Jan 13 18:35:33 Rescue kernel: [ 104.657485] [<ffffffffa04709aa>] walk_down_log_tree+0x15a/0x3e0 [btrfs] Jan 13 18:35:33 Rescue kernel: [ 104.657742] [<ffffffffa0470f57>] walk_log_tree+0xc7/0x1f0 [btrfs] Jan 13 18:35:33 Rescue kernel: [ 104.657990] [<ffffffffa0474d2c>] btrfs_recover_log_trees+0x1ec/0x2d0 [btrfs] Jan 13 18:35:33 Rescue kernel: [ 104.658244] [<ffffffffa0441c63>] open_ctree+0x13c3/0x1740 [btrfs] Jan 13 18:35:33 Rescue kernel: [ 104.658357] [<ffffffffa04206d3>] btrfs_fill_super.isra.36+0x73/0x150 [btrfs] Jan 13 18:35:33 Rescue kernel: [ 104.658395] [<ffffffffa0421ac9>] btrfs_mount+0x359/0x3e0 [btrfs] Jan 13 18:35:33 Rescue kernel: [ 104.658424] [<ffffffff8114e185>] mount_fs+0x45/0x1d0 Jan 13 18:35:33 Rescue kernel: [ 104.658437] [<ffffffff81166736>] vfs_kern_mount+0x66/0xd0 Jan 13 18:35:33 Rescue kernel: [ 104.658448] [<ffffffff81167ac3>] do_kern_mount+0x53/0x120 Jan 13 18:35:33 Rescue kernel: [ 104.658458] [<ffffffff81169575>] do_mount+0x1a5/0x260 Jan 13 18:35:33 Rescue kernel: [ 104.658470] [<ffffffff81169a1a>] sys_mount+0x9a/0xf0 Jan 13 18:35:33 Rescue kernel: [ 104.658481] [<ffffffff81543e12>] system_call_fastpath+0x16/0x1b Jan 13 18:35:33 Rescue kernel: [ 104.658495] [<00007f5e188f4daa>] 0x7f5e188f4da9 Jan 13 18:35:33 Rescue kernel: [ 104.658500] ---[ end trace b339d3701a74932f ]--- Jan 13 18:35:33 Rescue kernel: [ 104.658531] unable to find logical 20890721841152 len 4096 Jan 13 18:35:33 Rescue kernel: [ 104.658558] ------------[ cut here ]------------ Jan 13 18:35:33 Rescue kernel: [ 104.658567] kernel BUG at /home/abuild/rpmbuild/BUILD/kernel-default-3.1.0/linux-3.1/fs/btrfs/volumes.c:2891!
