Proxmox GPU Passthrough stopped working and dpkg problems

[Proxmoxbeginner30]

Hello, to all Proxmox fans,
I use a pve host with the following hardware:
Intel i5 10400
Asrock b460m Pro 4
64GB Corsair DDR4 RAM
4 SSD hard disks
2 HDD hard disks
AMD RX 570 from ASUS including vendor reset

Now it stopped working for my Linux VM, but in Windows 10 VM it worked perfect.
I want to try with new kernel but cant install them always dpkg error like :

apt --fix-broken install

Any help or workaround for this?

That is weird and suggest a problem with your GRUB configuration file. Please show the output of cat /etc/default/grub (in CODE-tags please).

GRUB_CMDLINE_LINUX_DEFAULT=intel_iommu=on "quiet"

That does not seem right.

Probably should be:

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on"

 

[leesteken]

GRUB_CMDLINE_LINUX_DEFAULT=intel_iommu=on "quiet"

Also, you don't need intel_iommu=on anymore since Proxmox kernel version 6.8. GRUB_CMDLINE_LINUX_DEFAULT="quiet" should work the same.

Ok thx for that i will give them a try . I changed grub like this and Ioomu worked without intel_iommu=on, but only windows vm got a picture. My Linux VM stays black screen. iam going to update kernel now to 6.8.12-7-pve-signed.
Cant install vendor-reset always get

modprobe vendor-reset
modprobe: FATAL: Module vendor-reset not found in directory /lib/modules/6.8.12-7-pve

Can anyone help me with older kernel got same error. Im getting back to 6.8.12-4 now vendor reset is working but always black screen for my linux vm. Windows VM works always

On Linux VM always get

bash: /sys/bus/pci/devices/0000:01:00.1/reset_method: Permission denied

vendor-reset works only half device not resetting audio from gpu but why?

sporadically i can get a picture of login screen, but after shutdown the vm i cant get picture anymore but vendor reset works
Got workaround: You need to remove GPU and then add it back again, so i can get picture
