Hi, I guess the following is a BIOS issue I need to take up with Supermicro.
I have a Supermicro X7DWE 5400 chipset based board I am using with a dual 82598EB 10Gb card and kernel 2.6.35.4 ioatdma: Intel(R) QuickData Technology Driver 4.00 alloc irq_desc for 57 on node -1 alloc kstat_irqs on node -1 ioatdma 0000:00:0f.0: PCI INT A -> GSI 57 (level, low) -> IRQ 57 ------------[ cut here ]------------ WARNING: at drivers/pci/intel-iommu.c:3056 quirk_ioat_snb_local_iommu+0xb1/0xcb() Hardware name: X7DWE BIOS assigned incorrect VT-d unit for Intel(R) QuickData Technology device Modules linked in: ioatdma(+) i5k_amb hwmon iTCO_wdt iTCO_vendor_support snd_pcsp mdio snd_seq_dummy snd_seq_oss snd_seq_midi_event tpm_tis i5400_edac snd_seq mptsas(+) mptscsih mptbase tpm snd_seq_device tpm_bios i2c_i801 i2c_core snd_pcm_oss snd_mixer_oss snd_pcm snd_timer shpchp dca edac_core e1000e snd soundcore snd_page_alloc scsi_transport_sas floppy raid456 async_raid6_recov async_pq raid6_pq async_xor xor async_memcpy async_tx raid1 Pid: 323, comm: modprobe Not tainted 2.6.35.4 #1 Call Trace: [<ffffffff8122dd13>] ? quirk_ioat_snb_local_iommu+0xb1/0xcb [<ffffffff8104d575>] warn_slowpath_common+0x85/0xb3 [<ffffffff8104d625>] warn_slowpath_fmt_taint+0x66/0x68 [<ffffffff8138ca16>] ? pci_conf1_read+0xd9/0xe7 [<ffffffff8138e3b3>] ? raw_pci_read+0x23/0x3b [<ffffffff81215763>] ? pci_bus_read_config_dword+0x7a/0x8c [<ffffffff8122dd13>] quirk_ioat_snb_local_iommu+0xb1/0xcb [<ffffffff8121f7e9>] pci_fixup_device+0x115/0x140 [<ffffffff8121a735>] do_pci_enable_device+0x3e/0x45 [<ffffffff8121a796>] __pci_enable_device_flags+0x5a/0x6e [<ffffffff8121a7bd>] pci_enable_device+0x13/0x15 [<ffffffff8121a83e>] pcim_enable_device+0x7f/0x9f [<ffffffffa01eaf48>] ioat_pci_probe+0x18/0x1a0 [ioatdma] [<ffffffff8121aa29>] local_pci_probe+0x17/0x1b [<ffffffff8121b7c8>] pci_device_probe+0xcb/0xf5 [<ffffffff812bc4a6>] ? driver_sysfs_add+0x51/0x77 [<ffffffff812bc6cf>] driver_probe_device+0x132/0x26e [<ffffffff812bc868>] __driver_attach+0x5d/0x80 [<ffffffff812bc80b>] ? __driver_attach+0x0/0x80 [<ffffffff812bbd7a>] bus_for_each_dev+0x53/0x89 [<ffffffff812bc400>] driver_attach+0x21/0x23 [<ffffffff812bb5b6>] bus_add_driver+0xdc/0x24c [<ffffffff812bcb6e>] driver_register+0xb8/0x126 [<ffffffffa013e000>] ? ioat_init_module+0x0/0x83 [ioatdma] [<ffffffff8121b9ed>] __pci_register_driver+0x56/0xc1 [<ffffffffa013e000>] ? ioat_init_module+0x0/0x83 [ioatdma] [<ffffffffa013e06b>] ioat_init_module+0x6b/0x83 [ioatdma] [<ffffffff8100206a>] do_one_initcall+0x5f/0x15a [<ffffffff8107dcb9>] sys_init_module+0x9f/0x1dd [<ffffffff81009cc2>] system_call_fastpath+0x16/0x1b ---[ end trace f6505374b9a0e1cf ]--- Disabling lock debugging due to kernel taint ioatdma 0000:00:0f.0: setting latency timer to 64 alloc irq_desc for 99 on node -1 alloc kstat_irqs on node -1 ioatdma 0000:00:0f.0: irq 99 for MSI/MSI-X alloc irq_desc for 100 on node -1 alloc kstat_irqs on node -1 ioatdma 0000:00:0f.0: irq 100 for MSI/MSI-X alloc irq_desc for 101 on node -1 alloc kstat_irqs on node -1 ioatdma 0000:00:0f.0: irq 101 for MSI/MSI-X alloc irq_desc for 102 on node -1 alloc kstat_irqs on node -1 ioatdma 0000:00:0f.0: irq 102 for MSI/MSI-X ioatdma 0000:00:0f.0: APICID_TAG_MAP set incorrectly by BIOS, disabling DCA md/raid1:md3: active with 2 out of 2 mirrors md3: detected capacity change from 0 to 16006250496 md3: ixgbe: Intel(R) 10 Gigabit PCI Express Network Driver - version 2.1.4-NAPI Copyright (c) 1999-2010 Intel Corporation. ixgbe 0000:04:00.0: PCI INT A -> GSI 54 (level, low) -> IRQ 54 ixgbe 0000:04:00.0: setting latency timer to 64 md: bind<sda3> unknown partition table md: bind<sda12> md/raid1:md2: active with 2 out of 2 mirrors md2: detected capacity change from 0 to 518062080 md2: unknown partition table alloc irq_desc for 103 on node -1 alloc kstat_irqs on node -1 ixgbe 0000:04:00.0: irq 103 for MSI/MSI-X alloc irq_desc for 104 on node -1 alloc kstat_irqs on node -1 ixgbe 0000:04:00.0: irq 104 for MSI/MSI-X alloc irq_desc for 105 on node -1 alloc kstat_irqs on node -1 ixgbe 0000:04:00.0: irq 105 for MSI/MSI-X alloc irq_desc for 106 on node -1 alloc kstat_irqs on node -1 ixgbe 0000:04:00.0: irq 106 for MSI/MSI-X alloc irq_desc for 107 on node -1 alloc kstat_irqs on node -1 ixgbe 0000:04:00.0: irq 107 for MSI/MSI-X ixgbe: 0000:04:00.0: ixgbe_init_interrupt_scheme: Multiqueue Enabled: Rx Queue count = 4, Tx Queue count = 4 ixgbe: eth0: ixgbe_probe: No DCA provider found.
