I tried running 'lspci -nns 0000:10:00.0' but this hung the terminal. Virtual Machine Manager was now showing it couldn't connect to the KVM daemon. I rebooted the Host OS but running 'lspci -nns 0000:10:00.0' again hung and I still couldn't start the VM with GPU passthrough. Extra info: After installing updates to the Host OS on 2025-4-10, VMs without GPU passthrough worked fine. On 2025-4-12 I tried to start a VM with GPU passthrough but it wouldn't start. On 2025-4-10 one of the Host OS updates was linux-firmware:amd64 (20240318.git3b128b60-0ubuntu2.10 -> 20240318.git3b128b60-0ubuntu2.11). I wanted to test downgrading the linux-firmware back to version 2.10 but that is no longer available. I was able to find, from this launchpad, the files that were in the 2.10 and 2.11 versions of linux- firmware. I found the differences between the files for the amdgpu firmware files. I overwrote the /lib/firmware/amdgpu files on my host OS with the files from 2.10 and rebooted - the VM with GPU passthrough was able to start (and the lspci command worked.) The list of amdgpu firmware files I overwrote was: gc_11_5_1_imu.bin.zst gc_11_5_1_me.bin.zst gc_11_5_1_mec.bin.zst gc_11_5_1_mes1.bin.zst gc_11_5_1_mes_2.bin.zst gc_11_5_1_pfp.bin.zst gc_11_5_1_rlc.bin.zst isp_4_1_1.bin.zst psp_14_0_1_ta.bin.zst psp_14_0_1_toc.bin.zst sdma_6_1_1.bin.zst vcn_4_0_6_1.bin.zst vcn_4_0_6.bin.zst vpe_6_1_1.bin.zst --- ProblemType: Bug ApportVersion: 2.28.1-0ubuntu3.5 Architecture: amd64 CRDA: N/A CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Dependencies: firmware-sof-signed 2023.12.1-1ubuntu1.4 DistroRelease: Ubuntu 24.04 InstallationDate: Installed on 2024-06-01 (326 days ago) InstallationMedia: Ubuntu 24.04 LTS "Noble Numbat" - Release amd64 (20240424) MachineType: Gigabyte Technology Co., Ltd.
