@onionfx: Looks good to me. Thanks! It seems that all affected people are on Linux Mint. Is there anyone here who is running a flavor of Ubuntu itself? If not, could it be that Ubuntu itself never rolled out the -160 kernel to its users? Or if they did roll it out, that it went together with some firmware update that didn't make into into Mint?
The main report on the Linux Mint forum is: https://forums.linuxmint.com/viewtopic.php?p=2693612 . Anyway, when I boot the -160 kernel without "quiet splash", the last line that I see printed to the console is one of these three: [ 1.527044] kernel: [drm] VCN decode is enabled in VM mode [ 1.527789] kernel: [drm] VCN encode is enabled in VM mode [ 1.528534] kernel: [drm] JPEG decode is enabled in VM mode That is: the screen stops updating immediately after the DRM part of the amdgpu kernel module is enabled, and a second later goes black. Like Howard, afterward I then see these lines in the relevant /var/log.Xorg.0.log.old file: [ 4.854] (EE) AMDGPU(0): failed to set mode: Invalid argument [ 4.854] (WW) AMDGPU(0): Failed to set mode on CRTC 0 [ 4.854] (EE) AMDGPU(0): Failed to enable any CRTC ** Attachment added: "Xorg.0.log.old" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2128729/+attachment/5920296/+files/Xorg.0.log.old -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2128729 Title: Kernel 5.15.0-160 boots without any video output (on AMD) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2128729/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
