Bug ID: 107913
Summary: amdgpu_drv.so segfaults on boot; black screen
Product: xorg
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/AMDgpu
Assignee: xorg-driver-ati@lists.x.org

Xorg.0.log including the segfoult
History (maybe only partly related to the problem):
I followed this guide to update my drivers:
https://github.com/ValveSoftware/Proton/blob/proton_3.7/PREREQS.md
sudo add-apt-repository ppa:paulo-miguel-dias/mesa
sudo apt dist-upgrade
sudo apt install mesa-vulkan-drivers mesa-vulkan-drivers:i386
which worked fine for some days. I updated my system as normal (via apt) and
after a reboot the machine came up with a black screen.
I found a segfault in my Xorg.0.log (attached). Blacklisting the module
"amdgpu" lets me boot into the desktop using only the integrated Intel GPU.
Some information that are hopefully helpful:
$ lspci -k
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620 (rev 02)
Subsystem: Dell HD Graphics 620
Kernel driver in use: i915

Kernel modules: amdgpu
$ uname -a
Linux notebook-kai 4.15.0-34-generic #37-Ubuntu SMP Mon Aug 27 15:21:48 UTC
2018 x86_64 x86_64 x86_64 GNU/Linux
My PC is a notebook with an integrated Intel GPU and a dedicated AMD GPU.
OS is Linux Mint 19 Cinnamon
CPU is Intel© Core™ i7-7500U CPU @ 2.70GHz × 2
What else is needed?
Can I somehow re-install or downgrade the amdgpu-drivers?
