Passthrough RTX 5090 CPU Soft BUG lockup, D3cold to D0, after guest shutdown

Trying some 4 extra parameters to see if it will help or not. Will report when issue happens again.

quiet idle=nomwait pci=nocrs pci=realloc processor.max_cstate=5 amd_iommu=on iommu=pt vfio_iommu_type1.allow_unsafe_interrupts=1 vfio-pci.ids=10de:22e8,10de:2bb1 initcall_blacklist=sysfb_init
 
Have a look at the attachment:
So the upgrading firmware did not help. I am looking for next steps. Already wrote to asrock support, also i will write to nvidia but i think it might be motherboard issue. And thinking what more can i do more.
Anyway i would like to thank you for your suggestion. If you need for example RTX5090 or 6000 to use for a while in VM then i do have datacenter on which i am renting those bu i can rent for free for some time if you would need it.
The scripts you sent i will check out later once i will have this stable.
 
Those commands did not help.
I am currently speaking to Nvidia enterprise support Tier II to fix this. They asked me to talk with Proxmox support team so i also sent them support ticket.
 
Hi!
I have basically the same problem and opened another threat:

I think I tried the firmware update aswell, but I am not quite sure about it.

Is there any help at the moment?

Today i got answer from Proxmox. It is not my proxmox installation and it was installed from clean debian. But here it is:

pve-edk2-firmware: not correctly installed
According to the report, the package is not installed correctly, which may affect EFI VMs. Please reinstall:

Code:
apt update
apt install --reinstall pve-edk2-firmware
# Check if apt is ok:
apt -f install

# You could also try testing Optin Kernel 6.14. This has fixed a GPU theme in the past.

apt install proxmox-kernel-6.14
