Hi Bart, The fix (http://marc.info/?l=linux-scsi&m=138696701824443&w=2) for this issue is submitted today. ~Saurav >Hello, > >Apparently trying to load the qla2xxx kernel module with parameter >ql2xmultique_tag=1 triggers a kernel oops. This is 100% reproducible >with at least kernel versions 3.11.8 and 3.13-rc3. Has anybody else >run into this before ? > >Thanks, > >Bart. > ># rmmod qla2xxx; dmesg -c >/dev/null; insmod >/lib/modules/3.13.0-rc3+/kernel/drivers/scsi/qla2xxx/qla2xxx.ko >ql2xmultique_tag=1; ql2xextended_error_logging=0x40100000; dmesg -c >Segmentation fault > >qla2xxx [0000:00:00.0]-0005: : QLogic Fibre Channel HBA Driver: >8.06.00.08-k-debug. >qla2xxx [0000:01:00.0]-0807: : Mem only adapter. >qla2xxx [0000:01:00.0]-0808: : Bars=74. >qla2xxx [0000:01:00.0]-080a: : Memory allocated for ha=ffff8800bf148000. >qla2xxx [0000:01:00.0]-080b: : device_type=0x9c000800 port=1 >fw_srisc_address=0x100000. >qla2xxx [0000:01:00.0]-081e: : mbx_count=32, req_length=2048, >rsp_length=512, max_loop_id=2047, init_cb_size=5252, >gid_list_info_size=8, optrom_size=2097152, nvram_npiv_size=256, >max_fibre_devices=2048. >qla2xxx [0000:01:00.0]-081f: : isp_ops=ffffffffa056ca80, >flash_conf_off=2147287040, flash_data_off=2146435072, >nvram_conf_off=2147418112, nvram_data_off=2147352576. >qla2xxx [0000:01:00.0]-0818: : MQIO Base=ffffc90015080000. >qla2xxx [0000:01:00.0]-001a: : MSI-X vector count: 31. >qla2xxx [0000:01:00.0]-081c: : MSIX Count:6. >qla2xxx [0000:01:00.0]-001d: : Found an ISP2532 irq 16 iobase >0xffffc9000007a000. >qla2xxx [0000:01:00.0]-0820: : 64 Bit addressing is enable. >qla2xxx [0000:01:00.0]-0822: : init_cb=ffff8800877ba000 >gid_list=ffff88008dfac000, srb_mempool=ffff88008dffeeb8 >s_dma_pool=ffff88008dffe080. >qla2xxx [0000:01:00.0]-0825: : dl_dma_pool=ffff88008dfff2c8 >fcp_cmnd_dma_pool=ffff88008dffc820. >qla2xxx [0000:01:00.0]-0827: : ms_iocb=ffff8800872e4000 >ct_sns=ffff8800d7b98000. >qla2xxx [0000:01:00.0]-082c: : req=ffff88008dffc208 req->length=2048 >req->ring=ffff880087240000 rsp=ffff8800bdcf9b60 rsp->length=512 >rsp->ring=ffff88008df70000. >qla2xxx [0000:01:00.0]-0923: : loop_id_map=ffff8800bdcf8ff8. >qla2xxx [0000:01:00.0]-0841:16: Allocated the host=ffff8800d36bb3d8 >hw=ffff8800bf148000 vha=ffff8800d36bbd50 dev_name=0000:01:00.0 >qla2xxx [0000:01:00.0]-0832:16: can_queue=2176, req=ffff88008dffc208, >mgmt_svr_loop_id=10, sg_tablesize=1024. >qla2xxx [0000:01:00.0]-0833:16: max_id=2048 this_id=-1 cmd_per_len=3 >unique_id=16 max_cmd_len=16 max_channel=0 max_lun=65535 >transportt=ffff8800a971d668, vendor_id=72057594037932151. >qla2xxx 0000:01:00.0: irq 49 for MSI/MSI-X >qla2xxx 0000:01:00.0: irq 50 for MSI/MSI-X >qla2xxx 0000:01:00.0: irq 67 for MSI/MSI-X >qla2xxx 0000:01:00.0: irq 68 for MSI/MSI-X >qla2xxx 0000:01:00.0: irq 69 for MSI/MSI-X >qla2xxx 0000:01:00.0: irq 70 for MSI/MSI-X >general protection fault: 0000 [#1] SMP >Modules linked in: qla2xxx(+) fuse ip6table_filter ip6_tables >iptable_filter ip_tables ebtable_nat ebtables x_tables af_packet bridge >stp llc rdma_ucm rdma_cm iw_cm ib_addr ib_srp scsi_transport_srp scsi_tgt >ib_ipoib ib_cm ib_uverbs ib_umad mlx4_en mlx4_ib ib_sa ib_mad ib_core >hid_generic usbhid hid snd_hda_codec_hdmi snd_hda_codec_realtek >snd_hda_intel snd_hda_codec r8169 snd_hwdep snd_pcm x86_pkg_temp_thermal >kvm_intel snd_seq kvm mii crc32c_intel snd_timer snd_seq_device i2c_i801 >mlx4_core snd lpc_ich sr_mod pcspkr mfd_core microcode soundcore ehci_pci >snd_page_alloc sg cdrom acpi_cpufreq ehci_hcd scsi_transport_fc wmi >autofs4 ext4 jbd2 mbcache crc16 raid456 async_raid6_recov async_pq >raid6_pq async_xor xor async_memcpy async_tx raid10 raid0 raid1 sd_mod >crc_t10dif crct10dif_common ahci xhci_hcd libahci usbcore usb_common i915 >drm_kms_helper drm intel_agp i2c_algo_bit intel_gtt agpgart i2c_core fan >thermal video button processor thermal_sys hwmon scsi_dh_alua scsi_dh >pata_ > acpi liba >ta scsi_mod [last unloaded: qla2xxx] >CPU: 3 PID: 4173 Comm: insmod Tainted: G W 3.13.0-rc3+ #1 >Hardware name: Gigabyte Technology Co., Ltd.
