 Question |
I have a Supermicro X8DTH-iF motherboard and have been successfully running ESX 4.0.
I upgraded to ESX 4.1 and the machine crashed with a purple screen.
If I turned of VT-d support (Northbridge) in the BIOS was running again, but the pass-through-mode is not working.
I upgraded the bios to 2.0, but there is no effect. This might be an BIOS defect in the ACPI Direct Memory Access remapping. |

Please check the attached BIOS (8DTH9170.zip) which can meet the Intel VT-d spec. http://download.intel.com/technology/computing/vptech/Intel(r)_VT_for_Direct_IO.pdf
But it also needs OS explanation. This is related topic to this issue - http://www.vmware.com/support/vsphere4/doc/vsp_esx41_vc41_rel_notes.html
ยท PCI device mapping errors on 370 G6 HP server When you run I/O operations on the 370 G6 HP server, you might encounter a purple screen or see alerts about "Lint1 Interrupt" or NMI on the console. The HP ProLiant DL370 G6 server has two Intel I/O hub (IOH)s and a BIOS defect in the ACPI Direct Memory Access remapping (DMAR) structure definitions, which causes some PCI devices to be incorrectly described under the wrong DMA remapping unit. Any DMA access by such incorrectly described PCI devices trigger an IOMMU fault and the device will receive an I/O error. Depending on the device, this I/O error might result in an Lint1 Interrupt or NMI alert message on the console or the system might freeze with a purple screen.
Workaround: Check the HP Web site for availability of a BIOS patch for the HP ProLiant DL370 G6 server. If a patch is not available, disable "Intel(R) VT-d" in the BIOS so that the BIOS will not publish DMAR structures in the ACPI tables. |
