Well, there doesn't appear to be any reference to a setting in my BIOS for this size(IOMMU). So I don't think that I can change it! :( The machine is working quite a bit better with pci=noacpi in leu of disabling ACPI in the BIOS, but there are still those nasty errors in reference to the ACPI tables being broken: ACPI-0362: *** Error: Looking up [\_SB_.PCI0.LNK0] in namespace, AE_NOT_FOUND search_node ffff8101428572c0 start_node ffff8101428572c0 return_node 0000000000000000 And this one about the 8254 timer: ..MP-BIOS bug: 8254 timer not connected to IO-APIC And finally, I think that something else kind of wierd is happening with the on-board sensors. lm_sensors is having trouble detecting the fan speeds and temperatures of the main board, but I will take that up with their developers.
