So, I can confirm that these errors are GPU passthrough related. As long as i'm not trying to passthrough a PCI device there are no errors and the windows 10 VM works as it should. Now as soon as I passthrough my rtx2080 for the guest (a gtx 960 for host) The Vm spits out ext4-fs errors (see crash2 picture, sorry for the bad quality but I couldn't find any logs of it and my camera is broken). The syslog reports RRDC/RRD errors (see picture crash). Storage is not the problem. Output attached. Vm gets stuck and I have to hard reset or it just reboots after hanging a few seconds.
Configurations found in attached pictures.

Thanks in advance

Hardware specs:
ryzen1700x
ax370 gaming k7
rtx2080, gtx960

first please upgrade your host to a current version (maybe some update already fixed it)
second, maybe your disks(sata controller/nvme) are in the same iommu group as your graphics card?

I found that the current version doesn't bind my vfio drivers at all. I have an acs override patch enabled and all iommu groups are separated.
