You hit this in ext4_put_super() during umount: /* Debugging code just in case the in-memory inode orphan list * isn't empty. The on-disk one can be non-empty if we've * detected an error and taken the fs readonly, but the * in-memory list had better be clean by this point. */ if (!list_empty(&sbi->s_orphan)) dump_orphan_list(sb, sbi); J_ASSERT(list_empty(&sbi->s_orphan)); any chance you've got anything crazy going on like mounting the same loop file on 2 machines via an nfs export, or anything else out of the ordinary? If you mount it and do "find -inum 32017 /mount/point" for each of the inode numbers below, do the files in question have anything unique going on? -Eric > > 2013-05-16T22:17:20.984+02:00 n22 kernel: EXT4-fs (loop0): sb orphan head is 32017 > 2013-05-16T22:17:20.984+02:00 n22 kernel: sb_info orphan list: > 2013-05-16T22:17:20.984+02:00 n22 kernel: inode loop0:32017 at d9ed5a50: mode 103777, nlink 0, next 32003 > 2013-05-16T22:17:20.984+02:00 n22 kernel: inode loop0:32003 at dfde6d10: mode 102777, nlink 0, next 32021 > 2013-05-16T22:17:20.984+02:00 n22 kernel: inode loop0:32021 at d9ed6158: mode 103777, nlink 0, next 32013 > 2013-05-16T22:17:20.984+02:00 n22 kernel: inode loop0:32013 at d9ed55a0: mode 103777, nlink 0, next 0 > 2013-05-16T22:17:20.984+02:00 n22 kernel: ------------[ cut here ]------------ > 2013-05-16T22:17:20.984+02:00 n22 kernel: kernel BUG at fs/ext4/super.c:804! > 2013-05-16T22:17:20.984+02:00 n22 kernel: invalid opcode: 0000 [#1] SMP > 2013-05-16T22:17:20.984+02:00 n22 kernel: Modules linked in: dm_crypt cpufreq_stats loop nfsd auth_rpcgss oid_registry lockd sunrpc ipt_MASQUERADE xt_owner xt_multiport ipt_REJECT xt_tcpudp xt_recent xt_conntrack nf_conntrack_ftp xt_limit xt_LOG iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_nat nf_conntrack iptable_filter ip_tables x_tables af_packet pppoe pppox ppp_generic slhc bridge stp llc tun fuse dm_mod coretemp kvm_intel kvm hid_cherry aesni_intel uvcvideo xts aes_i586 videobuf2_vmalloc lrw videobuf2_memops gf128mul ablk_helper hid_generic arc4 usbhid videobuf2_core cryptd iwldvm mac80211 usblp videodev hid i915 snd_hda_codec_conexant snd_hda_intel iwlwifi cfg80211 cfbfillrect cfbimgblt i2c_algo_bit cfbcopyarea intel_agp intel_gtt snd_hda_codec snd_pcm fbcon snd_page_alloc bitblit softcursor font drm_kms_helper drm snd_timer psmouse tpm_tis 8250_pci thinkpad_acpi agpgart nvram sr_mod evdev snd tpm wmi 8250 serial_core i2c_i801 i2c_core cdrom sdhci_pci ! sd! > hci mmc_co > re soundcore acpi_cpufreq thermal mperf battery ac tpm_bios e1000e rfkill ptp video fb button fbdev pps_core processor thermal_sys hwmon [last unloaded: microcode] > 2013-05-16T22:17:20.984+02:00 n22 kernel: CPU: 1 PID: 9391 Comm: umount Not tainted 3.10.0-rc1+ #1 > 2013-05-16T22:17:20.984+02:00 n22 kernel: Hardware name: LENOVO 4180F65/4180F65, BIOS 83ET73WW (1.43 ) 11/30/2012 > 2013-05-16T22:17:20.984+02:00 n22 kernel: task: eab54290 ti: d6cfc000 task.ti: d6cfc000 > 2013-05-16T22:17:20.984+02:00 n22 kernel: EIP: 0060:[<c11bcb8c>] EFLAGS: 00010283 CPU: 1 > 2013-05-16T22:17:20.984+02:00 n22 kernel: EIP is at ext4_put_super+0x2dc/0x2e0 > 2013-05-16T22:17:20.984+02:00 n22 kernel: EAX: 0000003d EBX: e7adbc00 ECX: e7adbd50 EDX: e7adbd50 > 2013-05-16T22:17:20.984+02:00 n22 kernel: ESI: e7addc00 EDI: e7adbd14 EBP: d6cfdefc ESP: d6cfdecc > 2013-05-16T22:17:20.984+02:00 n22 kernel: DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 > 2013-05-16T22:17:20.984+02:00 n22 kernel: CR0: 80050033 CR2: b76bd0c0 CR3: 2f41e000 CR4: 000407f0 > 2013-05-16T22:17:20.984+02:00 n22 kernel: DR0: 00000000 DR1: 00000000 DR2: 00000000 DR3: 00000000 > 2013-05-16T22:17:20.984+02:00 n22 kernel: DR6: ffff0ff0 DR7: 00000400 > 2013-05-16T22:17:20.984+02:00 n22 kernel: Stack: > 2013-05-16T22:17:20.984+02:00 n22 kernel: c155c130 e7adddbc 00007d0d d9ed55a0 000087ff 00000000 00000000 d9ed5580 > 2013-05-16T22:17:20.984+02:00 n22 kernel: e7adbd50 e7addc00 e7addc58 c14957a0 d6cfdf18 c111f441 d6cfdf28 d6cfdf18 > 2013-05-16T22:17:20.984+02:00 n22 kernel: f1fd4200 00000083 e7addc00 d6cfdf28 c111f4e9 e7addc00 c15f1e28 d6cfdf38 > 2013-05-16T22:17:20.984+02:00 n22 kernel: Call Trace: > 2013-05-16T22:17:20.984+02:00 n22 kernel: [<c111f441>] generic_shutdown_super+0x51/0xd0 > 2013-05-16T22:17:20.984+02:00 n22 kernel: [<c111f4e9>] kill_block_super+0x29/0x70 > 2013-05-16T22:17:20.984+02:00 n22 kernel: [<c111f734>] deactivate_locked_super+0x44/0x70 > 2013-05-16T22:17:20.984+02:00 n22 kernel: [<c1120107>] deactivate_super+0x47/0x60 > 2013-05-16T22:17:20.985+02:00 n22 kernel: [<c1136e8d>] mntput_no_expire+0xcd/0x120 > 2013-05-16T22:17:20.985+02:00 n22 kernel: [<c1137d4e>] SyS_umount+0xae/0x330 > 2013-05-16T22:17:20.985+02:00 n22 kernel: [<c1137fee>] SyS_oldumount+0x1e/0x20 > 2013-05-16T22:17:20.985+02:00 n22 kernel: [<c1477601>] sysenter_do_call+0x12/0x22 > 2013-05-16T22:17:20.985+02:00 n22 kernel: Code: 24 30 c1 55 c1 05 bc 01 00 00 89 44 24 04 e8 4d 22 2b 00 8b 4d ec 8b 55 f0 8b 09 39 ca 75 b2 39 93 50 01 00 00 0f 84 9a fe ff ff <0f> 0b 66 90 55 89 e5 83 ec 20 66 66 66 66 90 8d 45 18 c7 04 24 > 2013-05-16T22:17:20.985+02:00 n22 kernel: EIP: [<c11bcb8c>] ext4_put_super+0x2dc/0x2e0 SS:ESP 0068:d6cfdecc > 2013-05-16T22:17:20.985+02:00 n22 kernel: ---[ end trace 0970735cee52720b ]--- > -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
