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? :)

Todays new kernel dident fix my problem either.

Mini bump with this comment to hope someone have the same problem or a fix.
