Hi, I have an LSI 9211-4i card (aka SAS2004) with 4 drives attached. No RAID-related setup in the card's BIOS, I'm just using the drives directly. This is with kernel 2.6.33. The card starts up with [ 1.714458] mpt2sas version 03.100.03.00 loaded [ 1.714757] scsi0 : Fusion MPT SAS Host [ 1.715174] alloc irq_desc for 16 on node -1 [ 1.715175] alloc kstat_irqs on node -1 [ 1.715178] alloc irq_2_iommu on node -1 [ 1.715184] mpt2sas 0000:05:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 1.715431] mpt2sas 0000:05:00.0: setting latency timer to 64 [ 1.715435] mpt2sas0: 64 BIT PCI BUS DMA ADDRESSING SUPPORTED, total mem (12387344 kB) [ 1.715939] alloc irq_desc for 31 on node -1 [ 1.715941] alloc kstat_irqs on node -1 [ 1.715943] alloc irq_2_iommu on node -1 [ 1.715947] mpt2sas 0000:05:00.0: irq 31 for MSI/MSI-X [ 1.715960] mpt2sas0: PCI-MSI-X enabled: IRQ 31 [ 1.716199] mpt2sas0: iomem(0xfaefc000), mapped(0xffffc90001878000), size(16384) [ 1.716643] mpt2sas0: ioport(0xd000), size(256) [ 1.788476] mpt2sas0: sending diag reset !!

However it seems that running SMART commands (like smartctl -a, smartmontools 5.39) on the drives attached results in the following, semi-reliably: [ 7069.168433] DRHD: handling fault status reg 2 [ 7069.168440] DMAR:[DMA Read] Request device [05:00.0] fault addr e0000 [ 7069.168442] DMAR:[fault reason 06] PTE Read access is not set [ 7069.815775] mpt2sas0: fault_state(0x2665)!

Anything I can do to debug this? Should I turn DMAR off? The fault status reg changes with each attempt (2, 102, 202), but the fault address is always e0000. Actually, it only happened 3 times, and I can't get it to happen a 4th time... perhaps it wasn't SMART, or harder to reproduce than I thought originally. This still seems bad though.
