Oh man, the unspeakable things I had to do to get this to work! But I'm glad that I did. Basically - these parameters did not really do the trick, I got desperate, went through some old sketchy overclocking forums and found some custom modified UEFI image (my board had only BIOS), that was taken from rev 2 of the board and made to work with the rev 1 I have and flashed that. And voila - the UEFI actually had a VT-d setting. Now everything works Thanks for the help anyway!

Cool, I'll try these things in the evening. Don't really wanna lock myself out doing this from work. Thanks for the tips!

Here is the new output. https://1drv.ms/t/s!Ao8d3jJR_0D1g_g-t_m0xPimwjwXig Not the best messages there though: [ 8.116667] AMD IOMMUv2 driver by Joerg Roedel <jroedel@suse.de> [ 8.116735] AMD IOMMUv2 functionality not available on this system

That is what I did, except I used >> . The server went down for a reboot now, will post new output ASAP.

Thanks for the response! dmesg | grep IOMMU returns nothing. BIOS is the latest available version. I even found that there was some "beta" version available, but QFlash did not allow me to flash that, neither did the msdos flash tool. EDIT: there is only "virtualization: enabled" in the BIOS. Did not find anything else similar to VT-d or VT-x.

Hei guys! After being inspired by LTT videos about Unraid, I decided it's my time to dive in there as well. As I had some older hardware easily available (Dell Optiplex 790 sff), I decided to play around on that. I was able to set up IOMMU (1050ti gpu passthrough to a windows vm) on that Dell motherboard with an i5-2500s. But then I decided that I want to upgrade at least parts of my server (case, MB, CPU, additional drives, PSU). So now I have the following setup: i7-2600 GA-Z68AP-D3 rev 1.0 16GB DDR3 RAM bunch of drives, ssd's for cache This is working quite great for me as a home server (seafile, nas, plex, etc), but I also wanted to make a Windows VM with GPU passthrough to be able to do some light gaming on the living room TV. So I made all the cabling (10m hdmi, 10m active usb cables), plugged all in, went into BIOS, made sure the virtualization was enabled, but when booting into unraid, I get this: When googling about this issue with my particular motherboard, I came across this post, which does not seem too optimistic about IOMMU on this boad - link. ;( I am wondering if anyone has any tips or suggestions on what to actually try before I go about switching my board again.

Hi! This is my first post here. :) I just today visited the forums for the first time. When I saw the problem you described, I decided to sign up and share some of my experience. I Actually exprerienced a similar problem at my workplace upon enabling hyper-v. After some investigation, we decided to disable usb3 support in BIOS and voila! No more reboots and hyper-v working fine. You lose usb3 though. Let me know if this helps.
