elhoir, the next step is to fully commit bisect from Ubuntu kernel 4.19.0-7.8 to Ubuntu kernel 5.0.0-7.8. This will allow for a direct review of the offending commit(s) for either reverting, or further improvements. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ? This article was written for folks who don't know anything about linux, so it's easy to follow.
Please note, finding adjacent kernel versions, or providing a commit without testing it and reverting it is not fully commit bisecting. Also, the kernel release names are irrelevant for the purposes of bisecting. It is most helpful that after the bad commit (not kernel version) has been confirmed via testing, you then mark this report Status Confirmed. Thank you for your help. ** Attachment removed: "amdgpu-at-dmesg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1818580/+attachment/5244194/+files/amdgpu-at-dmesg ** Description changed: I cannot boot PC normally, i must use recovery mode. + + Full dmesg after modprobe'ing amdgpu demonstrating call trace and lead up: + https://launchpadlibrarian.net/414079136/complete-dmesg-after-modprobe-amdgpu.txt WORKAROUND: Use kernel parameter: nomodeset OR: modprobe.blacklist=amdgpu ProblemType: Bug DistroRelease: Ubuntu 19.04 Package: xserver-xorg-video-amdgpu 18.1.99+git20190207-1 ProcVersionSignature: Ubuntu 5.0.0-7.8-lowlatency 5.0.0 Uname: Linux 5.0.0-7-lowlatency x86_64 .tmp.unity_support_test.1: ApportVersion: 2.20.10-0ubuntu21 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None CurrentDesktop: XFCE Date: Tue Mar 5 00:59:48 2019 DistUpgraded: 2019-02-07 01:41:15,390 DEBUG Running PostInstallScript: './xorg_fix_proprietary.py' DistroCodename: disco DistroVariant: ubuntu GraphicsCard: Advanced Micro Devices, Inc.
