It''s a known bug (that ought to be fixed before the 3.9 release in fact). You can either use btrfs-next or apply the commits mentioned in my previous email today: On Tue, May 07, 2013 at 08:08 (+0200), Jan Schmidt wrote:> In git log order: > > 6ced2666 Btrfs: separate sequence numbers for delayed ref tracking and tree > mod log > ef9120b1 Btrfs: fix tree mod log regression on root split operations > 2ed098ca Btrfs: fix accessing the root pointer in tree mod log functions > 50723551 Btrfs: fix unlock after free on rewinded tree blocks > > The commit ids are from josef''s master branch > (git://git.kernel.org/pub/scm/linux/kernel/git/josef/btrfs-next.git) which is > known not to be very stable regarding commit ids.Either way should fix your problem. An alternative is to wait for a 3.9 stable release after those fixes are in mainline (which should happen within the next seven days, I hope). Not using defrag, autodefrag or qgroups might also be an effective workaround, but no guarantees on that. -Jan> May 7 01:57:33 caper kernel: [ 0.000000] Linux version > 3.9.0-030900-generic (apw@gomeisa) (gcc version 4.6.3 (Ubuntu/Linaro > 4.6.3-1ubuntu5) ) #201304291257 SMP Mon Apr 29 16:58:15 UTC 2013 > ... > May 7 02:09:21 caper kernel: [ 726.745485] ------------[ cut here > ]------------ > May 7 02:09:21 caper kernel: [ 726.745567] Kernel BUG at > ffffffffa00ea503 [verbose debug info unavailable] > May 7 02:09:21 caper kernel: [ 726.745643] invalid opcode: 0000 [#1] SMP > May 7 02:09:21 caper kernel: [ 726.745807] Modules linked in: > snd_hrtimer zram(C) bnep rfcomm bluetooth parport_pc ppdev nfsd > nfs_acl auth_rpcgss nfs fscache binfmt_misc lockd sunrpc > snd_hda_codec_hdmi joydev hid_gaff ff_memless snd_usb_ > audio snd_usbmidi_lib uvcvideo snd_seq_midi videobuf2_core videodev > snd_rawmidi videobuf2_vmalloc videobuf2_memops snd_seq_midi_event > dm_multipath snd_hda_codec_realtek snd_seq scsi_dh kvm_amd > snd_seq_device snd_hda_intel kvm snd_hda_codec > snd_hwdep microcode snd_pcm snd_timer k10temp edac_core edac_mce_amd > serio_raw snd sp5100_tco i2c_piix4 soundcore snd_page_alloc mac_hid > wmi it87 hwmon_vid lp parport xfs btrfs raid6_pq zlib_deflate xor > libcrc32c ses enclosure dm_crypt hi > d_generic usbhid hid usb_storage firewire_ohci firewire_core crc_itu_t > ahci pata_acpi pata_atiixp libahci r8169 > May 7 02:09:21 caper kernel: [ 726.749841] CPU 3 > May 7 02:09:21 caper kernel: [ 726.749900] Pid: 1703, comm: > btrfs-endio-wri Tainted: G C 3.9.0-030900-generic > #201304291257 Gigabyte Technology Co., Ltd. > GA-MA790GP-UD4H/GA-MA790GP-UD4H > May 7 02:09:21 caper kernel: [ 726.750069] RIP: > 0010:[<ffffffffa00ea503>] [<ffffffffa00ea503>] > __tree_mod_log_rewind+0x253/0x260 [btrfs] > May 7 02:09:21 caper kernel: [ 726.750244] RSP: > 0018:ffff88011a2e1838 EFLAGS: 00010293 > May 7 02:09:21 caper kernel: [ 726.750316] RAX: 0000000000000000 > RBX: ffff88004b2798f0 RCX: ffff88011a2e17d8 > May 7 02:09:21 caper kernel: [ 726.750390] RDX: 0000000013f3a75c > RSI: 00000000000005e8 RDI: ffff8800172ea880 > May 7 02:09:21 caper kernel: [ 726.750463] RBP: ffff88011a2e1868 > R08: 0000000000001000 R09: ffff88011a2e17e8 > May 7 02:09:21 caper kernel: [ 726.750536] R10: 00000000000103db > R11: 0000000000000000 R12: ffff880098cf4d80 > May 7 02:09:21 caper kernel: [ 726.750609] R13: 000000000000002b > R14: ffff8800172ea700 R15: 000000000009c7a7 > May 7 02:09:21 caper kernel: [ 726.750683] FS: > 00007fa2bc594700(0000) GS:ffff88014fd80000(0000) > knlGS:0000000000000000 > May 7 02:09:21 caper kernel: [ 726.750770] CS: 0010 DS: 0000 ES: > 0000 CR0: 000000008005003b > May 7 02:09:21 caper kernel: [ 726.750841] CR2: 00000000fd82c000 > CR3: 000000014654d000 CR4: 00000000000007e0 > May 7 02:09:21 caper kernel: [ 726.750914] DR0: 0000000000000000 > DR1: 0000000000000000 DR2: 0000000000000000 > May 7 02:09:21 caper kernel: [ 726.750987] DR3: 0000000000000000 > DR6: 00000000ffff0ff0 DR7: 0000000000000400 > May 7 02:09:21 caper kernel: [ 726.751061] Process btrfs-endio-wri > (pid: 1703, threadinfo ffff88011a2e0000, task ffff88004a6b2ea0) > May 7 02:09:21 caper kernel: [ 726.751147] Stack: > May 7 02:09:21 caper kernel: [ 726.751212] ffff88011a2e1858 > ffff880104c8de30 000000000009c7a7 ffff880000000000 > May 7 02:09:21 caper kernel: [ 726.751488] 00000000a8598000 > ffff880148278000 ffff88011a2e18b8 ffffffffa00ea5ef > May 7 02:09:21 caper kernel: [ 726.751763] ffff880098cf4d80 > ffff88004b2798f0 ffff8800338d3000 0000000000000001 > May 7 02:09:21 caper kernel: [ 726.752038] Call Trace: > May 7 02:09:21 caper kernel: [ 726.752135] [<ffffffffa00ea5ef>] > tree_mod_log_rewind+0xdf/0x240 [btrfs] > May 7 02:09:21 caper kernel: [ 726.752237] [<ffffffffa00f25cb>] > btrfs_search_old_slot+0x4cb/0x670 [btrfs] > May 7 02:09:21 caper kernel: [ 726.752351] [<ffffffffa016d118>] > __resolve_indirect_ref+0xc8/0x150 [btrfs] > May 7 02:09:21 caper kernel: [ 726.752462] [<ffffffffa016d23e>] > __resolve_indirect_refs+0x9e/0x200 [btrfs] > May 7 02:09:21 caper kernel: [ 726.752573] [<ffffffffa016da3d>] > find_parent_nodes+0x45d/0x6b0 [btrfs] > May 7 02:09:21 caper kernel: [ 726.752684] [<ffffffffa016dd29>] > btrfs_find_all_roots+0x99/0x100 [btrfs] > May 7 02:09:21 caper kernel: [ 726.752792] [<ffffffffa0119620>] ?
