Package: bcache-tools Version: 1.0.4-1 Severity: normal Dear Maintainer,
I'm using bcache to provide storage (through nfs) for virtual machines .The server was working for a month without any problems however last friday i got a bcache error that made the bcache device unusable. I couldn't detach the device from the cache and had to reboot. I got the following error from syslog: Jun 27 10:00:00 storage kernel: [859662.906019] BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 Jun 27 10:00:00 storage kernel: [859662.906073] IP: [<ffffffffa01b7771>] bch_btree_node_read_done+0x41/0x440 [bcache] Jun 27 10:00:00 storage kernel: [859662.906123] PGD 0 Jun 27 10:00:00 storage kernel: [859662.906135] Oops: 0002 [#1] SMP Jun 27 10:00:00 storage kernel: [859662.906154] Modules linked in: iscsi_trgt(O) crc32c nfsd auth_rpcgss oid_registry nfs_acl nfs lockd fscache sunrpc 8021q garp stp mrp llc bonding loop intel_powerclamp coretemp kvm_intel kvm crct10dif_pclmul iTCO_wdt ast iTCO_vendor_support ttm drm_kms_helper drm crc32_pclmul crc32c_intel ghash_clmulni_intel aesni_intel aes_x86_64 lrw gf128mul lpc_ich i2c_algo_bit ioatdma i2c_i801 i2c_core joydev evdev psmouse dca ipmi_si glue_helper acpi_cpufreq serio_raw pcspkr parport_pc ipmi_msghandler parport i7core_edac mfd_core edac_core ablk_helper cryptd processor thermal_sys button ext4 crc16 mbcache jbd2 dm_mod raid1 md_mod bcache sg sd_mod sr_mod crc_t10dif crct10dif_common cdrom hid_generic usbhid hid ahci libahci libata uhci_hcd ehci_pci ehci_hcd e1000e ptp pps_core 3w_sas usbcore usb_common scsi_mod Jun 27 10:00:00 storage kernel: [859662.906578] CPU: 1 PID: 23117 Comm: kworker/1:2 Tainted: G IO 3.14-0.bpo.1-amd64 #1 Debian 3.14.4-1~bpo70+1 Jun 27 10:00:00 storage kernel: [859662.906624] Hardware name: empty empty/S7002, BIOS 'V1.08E ' 10/19/2010 Jun 27 10:00:00 storage kernel: [859662.906659] Workqueue: bcache bch_data_insert_keys [bcache] Jun 27 10:00:00 storage kernel: [859662.906686] task: ffff8800ba0752f0 ti: ffff880002724000 task.ti: ffff880002724000 Jun 27 10:00:00 storage kernel: [859662.906719] RIP: 0010:[<ffffffffa01b7771>] [<ffffffffa01b7771>] bch_btree_node_read_done+0x41/0x440 [bcache] Jun 27 10:00:00 storage kernel: [859662.906769] RSP: 0018:ffff880002725b58 EFLAGS: 00010246 Jun 27 10:00:00 storage kernel: [859662.906794] RAX: 0000000000001000 RBX: ffff880135f59000 RCX: ffff8801b5e40000 Jun 27 10:00:00 storage kernel: [859662.906825] RDX: 0000000000000000 RSI: 0000000000000246 RDI: 0000000000000246 Jun 27 10:00:00 storage kernel: [859662.906857] RBP: 0000000000000000 R08: 0000000000000000 R09: 0000000000000f58 Jun 27 10:00:00 storage kernel: [859662.906888] R10: 0000000000001770 R11: 0000000000000000 R12: ffff8800b8a00000 Jun 27 10:00:00 storage kernel: [859662.906919] R13: ffff8801088c0020 R14: ffff8800ba0752f0 R15: 0000000000000000 Jun 27 10:00:00 storage kernel: [859662.906951] FS: 0000000000000000(0000) GS:ffff8801bf220000(0000) knlGS:0000000000000000 Jun 27 10:00:00 storage kernel: [859662.906987] CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b Jun 27 10:00:00 storage kernel: [859662.907013] CR2: 0000000000000008 CR3: 000000000180c000 CR4: 00000000000007e0 Jun 27 10:00:00 storage kernel: [859662.907044] Stack: Jun 27 10:00:00 storage kernel: [859662.907055] ffff880135f59000 ffff8800b88804e8 00030ddbdda6790d ffff8801088c0020 Jun 27 10:00:00 storage kernel: [859662.907093] ffff8800ba0752f0 ffffffffa01b7cc0 000000B0000000000 ffff8800ba0752f0 Jun 27 10:00:00 storage kernel: [859662.907130] 0000000000000000 0000000000000000 0000000000000000 00000000a0000001 Jun 27 10:00:00 storage kernel: [859662.907168] Call Trace: Jun 27 10:00:00 storage kernel: [859662.907189] [<ffffffffa01b7cc0>] ?
