Upgraded to version 9 of proxmox.
Ran the tester to check if everything was OK to upgrade. No problem there.
Then did the upgrade and it went trough.
After a reboot i got to the shell and webgui was working but after like 30 sec the computer froze. Didn't respond at all and no response from the shell at all sitting at the computer.
Narrowed it down to when opnsense initiated the Wan pcie interface card the computer froze.
If I removed the network cable it booted fine.
Next i noticed the pcie SAS card didn't work.
So backed to the old kernel and everything worked flawlessly.
Got to work with everything working with 20 seconds to spare

Anyone else had the same problems and know how to fix? :)

*edit*
Tried to create a new machine of opnsense with passtrough to my LAN card. Nothing changed so its probably kernel related.

Proxmox 9 ships with Kernel 6.14 which has issues with passing through sata/sas controllers to a VM. In my case, I couldn't boot my TrueNas VM which needed the ASM1064 SATA controller to be passed through.

The only solution for now seems to be downgrading to Kernel 6.8.

yeah both sas /sata and an intel network card dident work at all on that kernel.
Guess ill have to wait for a new kernel to be released and hope :)
 
Still a problem with newest kernel as of today.
Anything i can try to resolve this? :)

regards Joakim
 
Todays new kernel dident fix my problem either.

Mini bump with this comment to hope someone have the same problem or a fix.
 
You seem yo be suffering from the QEMU 10.0.2 issue (a part of the Proxmox 9 upgrade) which is effecting a number of device passthrough

See this thread for more details, it is discussing GPU passthrough but it's likely the same problem. In particular see the feedback from Dakralex

Thread 'updated to PVE 9.0 then GPU passthrough stopped working on Windows'

Previously the Intel 630 GPU passthrough is working fine on PVE 8 (for both Ubuntu and Windows 11).

Just now updated to 9.0, Windows - Device manager shows the device as error code 43. But if I passthrough the GPU to Ubuntu VM, it's working fine.

Checked these and verified the GPU should be successfully passed through (as Linux also can take that up)

Thanks

I have a similar issue with an iGPU passthrough, but mine is non-urgent so I can wait for an official fix.

First I suggest that you update the firmware on any effected devices, that has solve the issue for some with SATA Controller device passthrough.

The thread also suggests a later version of the pve-qemu-kvm package, as suggested by user takidding in the same thread, but I have not tried that myself.
Having read through the solution it is specific to Intel iGPU.

I would search the threads on here for your specific device to see if anyone else has solved the problem.

I hope that helps or at least points you in the right direction.

Thank you for this. I upgraded my ASM1064 SATA controller firmware as per this link and my issues with Kernel 6.14 seem to be resolved.
