dmar: DRHD Handling Fault

Hi All,

so i recently decided to build a best of a machine for unraid to run on.

i moved everything from my old setup to the new one and i am now getting the following error in the log every second

Apr 23 12:58:01 Storage kernel: dmar: DRHD: handling fault status reg 702

Apr 23 12:58:01 Storage kernel: dmar: DMAR:[DMA Read] Request device [04:00.0] fault addr ffe5a000

Apr 23 12:58:01 Storage kernel: DMAR:[fault reason 06] PTE Read access is not set

Apr 23 12:58:01 Storage kernel: dmar: DRHD: handling fault status reg 2

i have done some googling and come across this

https://bbs.archlinux.org/viewtopic.php?id=176398

however turning off visualization is not an option for me because i want to run VM's

the last suggestion on that page is to try intel_iommu=igfx_off so i edited the boot up options and put that in and unfortunately that did nothing , i tried playing around with the options inside the bios and tried with 1 video card and after a while the machine will just hang and stop responding. also when i do reboot the machine i have lost my cache configuration and i need to reset this every single time.

i have also tried the latest beta of unraid without any luck.

any suggestions would be greatly appreciated.

Thanks
