Hi all. I'd like to present the details of a kernel panic that I've encountered while using LIO Target with QLogic Fibre Channel adapters. Hopefully this is the correct place to post. If not please direct me to the appropriate address. I have set up LIO Target on a Super Micro server with a pair of dual port QLE2462 fibre channel host bus adapters. These are hooked into a pair of Brocade switches and presented to a pair of VMware ESXi 5.0 servers. I have a RAID-10 array made up of 8x 750GB SATA disks on a 3ware controller, which is presented as a 3000GB (approx 2.7GiB) LUN. I have managed to create a datastore and have presented it to the VMware servers. These see the disk okay and can see all available paths to it. I am running a Debian testing distribution on the Super Micro server. I have used the following command to clone the kernel sources with the target patches applied: git clone git://git.kernel.org/pub/scm/linux/kernel/git/nab/lio-core.git This pulled a kernel that identifies itself as version 3.1.0-rc10 I used the .config from the stock Debian 3.1 kernel as a basis for the configuraton options and enabled the TCM modules that I needed. On ESXi 5.0 I had to go into the advanced settings and change the value of DataMover.HardwareAcceleratedInit to 0 to silence a kernel message on the Super Micro server that was regularly being spit out when using the disk on the VMware servers. That message was long the lines of: "WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation" I have managed to create virtual machines and it mostly works well, but I have now had a couple of kernel OOPs occur, the first of which I didn't catch. However the most recent one I had an ssh session going on, and it spat messages to syslog so that I could get them. The details of the OOPs is as follows: kernel:[122001.107498] Call Trace: kernel:[122001.107605] Code: 89 ee bf 00 80 00 00 44 89 45 3c 45 8b 8c 24 88 03 00 00 89 44 24 10 41 8b 84 24 80 03 00 00 89 44 24 08 49 8b 84 24 60 01 00 00 <0f> b6 00 89 04 24 31 c0 e8 ad ae fe ff 66 81 4d 28 00 08 eb 5c kernel:[122001.107643] CR2: 0000000000000000 kernel:[122001.108383] Oops: 0000 [#2] SMP kernel:[122001.108597] Stack: kernel:[122001.108630] Call Trace: kernel:[122001.108834] Code: 3f 48 c1 e5 03 48 c1 e0 06 48 8d b0 c0 5d 40 81 48 29 ee e8 d7 2d fe ff 81 4b 14 00 00 00 04 41 59 5b 5d c3 48 8b 87 a0 02 00 00 kernel:[122001.108912] CR2: fffffffffffffff8 Nov 25 21:23:58 san kernel: [122001.107292] TARGET_CORE[qla2xxx]: Detected NON_EXISTENT_LUN Access for 0x00000001 Nov 25 21:23:58 san kernel: [122001.107305] TARGET_CORE[qla2xxx]: Detected NON_EXISTENT_LUN Access for 0x00000001 Nov 25 21:23:58 san kernel: [122001.107336] BUG: unable to handle kernel NULL pointer dereference at (null) Nov 25 21:23:58 san kernel: [122001.107340] IP: [<ffffffffa019ab1b>] qla_tgt_pre_xmit_response+0x1d0/0x2c0 [qla2xxx] Nov 25 21:23:58 san kernel: [122001.107362] PGD 0 Nov 25 21:23:58 san kernel: [122001.107365] Oops: 0000 [#1] SMP Nov 25 21:23:58 san kernel: [122001.107370] CPU 2 Nov 25 21:23:58 san kernel: [122001.107372] Modules linked in: target_core_pscsi target_core_file target_core_iblock tcm_fc libfc tcm_loop iscsi_target_mod tcm_qla2xxx target_core_mod configfs loop snd_pcm snd_timer snd soundcore snd_page_alloc radeon ttm drm_kms_helper drm i2c_algo_bit power_supply i2c_i801 parport_pc parport i2c_core i5000_edac edac_core shpchp ioatdma i5k_amb dca pci_hotplug pcspkr joydev rng_core processor container evdev psmouse serio_raw thermal_sys button ext4 mbcache jbd2 crc16 dm_mod sd_mod crc_t10dif usbhid hid sg sr_mod cdrom ata_generic uhci_hcd floppy ehci_hcd ata_piix libata qla2xxx scsi_transport_fc e1000 usbcore scsi_tgt 3w_9xxx e1000e scsi_mod [last unloaded: scsi_wait_scan] Nov 25 21:23:58 san kernel: [122001.107419] Nov 25 21:23:58 san kernel: [122001.107423] Pid: 31672, comm: kworker/2:2 Not tainted 3.1.0-rc10.lio+ #1 Supermicro X7DB8/X7DB8 Nov 25 21:23:58 san kernel: [122001.107428] RIP: 0010:[<ffffffffa019ab1b>] [<ffffffffa019ab1b>] qla_tgt_pre_xmit_response+0x1d0/0x2c0 [qla2xxx] Nov 25 21:23:58 san kernel: [122001.107441] RSP: 0018:ffff8800ae355c60 EFLAGS: 00010206 Nov 25 21:23:58 san kernel: [122001.107444] RAX: 0000000000000000 RBX: ffff880124c78800 RCX: ffffffffa01ae25d Nov 25 21:23:58 san kernel: [122001.107448] RDX: 000000000000e012 RSI: ffff8801257c0670 RDI: 0000000000008000 Nov 25 21:23:58 san kernel: [122001.107451] RBP: ffff8800ae355cf0 R08: 00000000000000ff R09: 000000000011adf0 Nov 25 21:23:58 san kernel: [122001.107454] R10: 0000000000008000 R11: 0000000000000020 R12: ffff8800cb17c800 Nov 25 21:23:58 san kernel: [122001.107457] R13: ffff8801257c0670 R14: ffff8800ae355d3c R15: 0000000000000002 Nov 25 21:23:58 san kernel: [122001.107461] FS: 0000000000000000(0000) GS:ffff88012fd00000(0000) knlGS:0000000000000000 Nov 25 21:23:58 san kernel: [122001.107465] CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b Nov 25 21:23:58 san kernel: [122001.107468] CR2: 0000000000000000 CR3: 0000000001605000 CR4: 00000000000006e0 Nov 25 21:23:58 san kernel: [122001.107471] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 Nov 25 21:23:58 san kernel: [122001.107474] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Nov 25 21:23:58 san kernel: [122001.107478] Process kworker/2:2 (pid: 31672, threadinfo ffff8800ae354000, task ffff880125638ab0) Nov 25 21:23:58 san kernel: [122001.107480] Stack: Nov 25 21:23:58 san kernel: [122001.107482] 0000000000000000 0000000000000000 0000000000000002 0000000000000000 Nov 25 21:23:58 san kernel: [122001.107488] ffff880124cc0000 0200000000000000 0000000000000000 ffff8800cb17cb00 Nov 25 21:23:58 san kernel: [122001.107494] ffff8801257c0670 0000000000000000 ffff8800cb17c800 0000000000000002 Nov 25 21:23:58 san kernel: [122001.107498] Call Trace: Nov 25 21:23:58 san kernel: [122001.107513] [<ffffffffa019ac67>] ?
