- Minor
I am running Unraid on bare metal, AsRock ROMED8-2T, AMD EPYC 7302P 16-Core @ 3000 MHz, 64 GiB DDR4 Multi-bit ECC
- I tried to create a TrueNAS VM in order to have access to ZFS and easier iSCSi
- It is well known that it is better to pass through a host controller as apposed to devices (be it USB, SATA, etc.)
- I tried TrueNAS core and TrueNAS scale (FreeBSD and Debian respectively)
- How ever I could not get the VM to start even to install the OS, this would also cause my whole server to crash requiring a hard reset.
- when I detached the SATA controller it would post
I saw that someone running Proxmox had this same issue:

https://forum.proxmox.com/threads/amd-epyc-pcie-passthrough-flr-error.106070/#post-456481
I used their work around as a fix
I unfortunately don't have a log, searched everywhere but found nothing that alluded to my issue (maybe I missed something)
Furthermore I documented my experience in more detail in the forum thread I created (linked below)
Please also note that I am not smart enough to understand why this is or was happening or why the fix worked
(punching this into my Unriad terminal: "echo bus >'/sys/bus/pci/devices/0000:47:00.0/reset_method'")
Nor do I know if this will happen with any VM or any onboard sata controller
But it does with a TrueNAS VM and with the the "AMD FCH SATA" controller.
I tried to follow the guidelines best I could, no logs but I can say that I deleted and recreated multiple different TrueNAS vm's and everyone failed to post without the command that I mentioned above
I followed Spaceinvader One's guide:

If I am mistaken in my discovery, this was an isolated event or the crashing was of my own doing feel free to delete this post.
(just not my other thread pls, it might help someone)
Thank you
