Updated: I was determined to fix this issue: 1) I downgrade the AMD drivers - NO CHANGE 2) Removed the AMD driver and reverted back to the stock Windows 10 driver - NO CHANGE 2) I moved the card to a different slot- NO CHANGE 3) I removed the card and replaced it with an older AMD card with support for the same drivers - FIXED I also put the card in a standalone Windows 10 machine (as I thought maybe there was a defect in the card) and it has run stable for over 24 hours now. I think the card is good. If you are using a AMD RX 5xx card via pass-thru to a Win 7 or Win10 machine please post and let me know if you have been successful. I know there have been alot of issues with the AMD RX cards with pass thru. Before I buy another one I want to make sure I am not going to have issues. Thanks

Whenever I run my Windows 7 or Windows 10 VM with my AMD RX 560 card passed thru the system runs for an hour or two and then the entire UNRAID system halts with the above error. I have done a number of google searches and I can not find what an error 40 means. Can anyone help? Solutions for other DMAR: DRHD errors is to add an line in the Kernel parameter intel_iommu=off Thanks George

I am running UNRAID 6.5.3 on a Dell 5820 Workstation, all runs well with my Linux VMs with several days uptime with no issues. Whenever I run my Win7-64 Bit VM the system runs fine when I am actively using it. However if I just leave the machine running I come back several hours later and the UNRAID system is froze. I see the Windows 7 desktop on one monitor and my Linux desktop on the others. I have tried to figure the issue out myself but to no avail. I have turned on debug mode and I am attacking the last logs before the system hangs. Sleep mode is turned off on all of the VMs and UNRAID. I have the Windows machine passed through to a Gigabyte AMD R560 GPU with the GPU BIOS passed thru. Please advise on any ideas. George unraid-diagnostics-20180908-2138.zip FCPsyslog_tail.txt
