Failed to boot OMV 4.1.22 ("AMD-Vi: Unable to write to IOMMU perf counter."), but OK with OMV 5.0.5

Hi all and a Happy New Year!

I tried to install the official OMV 4.1.22 (openmediavault_4.1.22-amd64.iso).
I manged to boot once OK. After some plaing around I rebooted and the machine hanged during boot (2 sec in the process) with
"AMD-Vi: Unable to write to IOMMU perf counter...". (I dont remember the exact fault - I lost my photo of the boot screen)
I reinstalled multiple times 4.1.22 from the USB, but never managed to boot afterwards.

At the end I gave up and installed the 5.x beta. And it worked.
But now I have some issues and I would like to go to a stable version.

I suspect that the kernel of 4.1.22 was not able to deal with my HW ( mP = AMD Ryzen 3 3200G, MoBo = Asus PRIME B450M-A)...

I think my option now is to downgrade the 5.0.5 to a 4.x using this procedure
https://forum.openmediavault.o…grading-to-newer-version/
Shall I pick using one openmediavault_4.1.22-1_all.deb (from http://packages.openmediavault…ol/main/o/openmediavault/)
Will i keep my current kernel?

Or shall I pick the latest 4.1.30? (openmediavault_4.1.30-1_all.deb)

Any other advice?

Zitat von Erinox

Why not try to fix the issues in OMV 5?

What are they? It's running quite stable for me. Might be easier than downgrading.

For example

The DLNA plugin seem not working with my other devices and I wanted to make sure it is not the OMV. (I didn't have time to dive into it)

I deleted some unused containers via Portainer and I lost the DNS configuration on the OMV network interface. o.0

This scared me thinking 5.x is not yet ready. I have very limited time and I don't want to spend it on the OMV core.

But maybe downgrading will eat more time? Is it even a sane thing to do?

Edit: Also, I saw post about OMV 6 web interface. This made me think the effort on 5.x. is low and it will be generally unstable version...

Another argument to go to 4.x is the plugins. For example, there is no VPN on 5.x

Thanks for the replies.

From all that I get the idea that downgrading is not a wise approach, right?
