After upgrading mesa to Xorg started freezing when starting certain applications.
Log snippet is attached

Additional info:
* package version(s)
mesa 19.2.0-2
libglvnd 1.2.0-1
lib32-mesa 19.2.0-2
lib32-libglvnd 1.2.0-1
lib32-libpcap 1.9.1-1
lib32-libva-mesa-driver 19.2.0-2
lib32-mesa-vdpau 19.2.0-2
lib32-vulkan-radeon 19.2.0-2

python-jinja 2.10.1-2
screen 4.7.0-1
vulkan-mesa-layer 19.2.0-2
vulkan-radeon 19.2.0-2
linux 5.3.1.arch1-1
* logs: see attachment
* hardware: see attached lshw.txt

Steps to reproduce:

Start Xorg with modesetting driver, start Signal Desktop ( - Xorg will freeze almost completely.

The only workaround is to downgrade mesa & related packages to the previous version:

sudo pacman -U /var/cache/pacman/pkg/mesa-19.1.7-1-x86_64.pkg.tar.xz /var/cache/pacman/pkg/libglvnd-1.1.1-1-x86_64.pkg.tar.xz /var/cache/pacman/pkg/lib32-mesa-19.1.7-1-x86_64.pkg.tar.xz /var/cache/pacman/pkg/lib32-libglvnd-1.1.1-1-x86_64.pkg.tar.xz /var/cache/pacman/pkg/lib32-libva-mesa-driver-19.1.7-1-x86_64.pkg.tar.xz /var/cache/pacman/pkg/lib32-mesa-vdpau-19.1.7-1-x86_64.pkg.tar.xz /var/cache/pacman/pkg/lib32-vulkan-radeon-19.1.7-1-x86_64.pkg.tar.xz /var/cache/pacman/pkg/libva-mesa-driver-19.1.7-1-x86_64.pkg.tar.xz /var/cache/pacman/pkg/mesa-vdpau-19.1.7-1-x86_64.pkg.tar.xz /var/cache/pacman/pkg/vulkan-mesa-layer-19.1.7-1-x86_64.pkg.tar.xz /var/cache/pacman/pkg/vulkan-radeon-19.1.7-1-x86_64.pkg.tar.xz

B.t.w., this behavior is quite similar to the one described in FS#61733.

Can confirm this, whole computer freezes. However, think it has to do with my RX 5700 XT, and that I need LLVM-9 for proper support.
Comment by Laurent Carlier (lordheavy) - Thursday, 03 October 2019, 14:44 GMT
Does it works with LTS kernel ?
Comment by Stanislav T (stas-t) - Thursday, 03 October 2019, 15:16 GMT
With LTS kernel (4.19.76-1-lts) it doesn't freeze indeed, thank you for the suggestion!

My computer freezes instantly after startup. I guess it's the graphical stuff of GNOME causing it after upgrading mesa to 19.2.0-2. I use a RX 5700 too but the system did not freeze with mesa 19.1.7-1 and even GNOME displayed. I assume the linux-kernel 5.3.1 and the navi-firmware was already enough for general rendering with the RX 5700, so I guess LLVM-9 won't just fix this problem.

I start X manually with fluxbox. X crashes and computer freezes even before it has even configured a screen. Cant even get a Xorg.0.log printout :) Works with 5.3.2 (custom) and mesa-19.1.7.
Comment by Andreas Radke (AndyRTR) - Friday, 04 October 2019, 05:20 GMT
Please report this to the Mesa devs even if some kernel drm bug may here be the cause.

Upgrading linux from 5.3.1.arch1-1 to 5.3.4.arch1-1 didn't solve the issue.
@kursu: What were the customizations for 5.3.2 kernel that fixed the problem for you?
@AndyRTR: You're right, it should be reported to mesa devs.

UPD: There is still no issue for LTS kernel after upgrading it from 4.19.76-1 to 4.19.77-1.

@stas-t no my problem is not fixed. I had to downgrade mesa. However I also had problem with the arch kernel not booting (
But a custom compiled kernel with the just needed options solved that problem

@kursu if you enable [1] is the issue still present?
If not if you rebuild mesa locally mesa 19.2 with the toolchain from mesa-git is the issue then present?

I can confirm that upgrading to 19.2.0-3 resolved the issue for me.
Comment by Tobias Frisch (TheJackiMonster) - Wednesday, 09 October 2019, 07:23 GMT
Upgrading to 19.2.0-3 worked.. I will test now if some freezes on demanding tasks still appear.

For me upgrading mesa/llvm-libs/compiler-rt/clang from testing didn't help - see:

UPD: current versions:
clang 9.0.0-2
compiler-rt 9.0.0-2
libva-mesa-driver 19.2.0-3
llvm-libs 9.0.0-2
mesa 19.2.0-3
mesa-vdpau 19.2.0-3
vulkan-mesa-layer 19.2.0-3
vulkan-radeon 19.2.0-3
gnome-builder 3.34.1-2
postgresql-libs 11.5-4
qt5-tools 5.13.1-2

@stas-t as you are encountering VM_L2_PROTECTION_FAULT_STATUS faults providing upstream with output from UMR [1] might help [2]
Have you also looked at bugs featuring VM_L2_PROTECTION_FAULT_STATUS [3]?

Mesa 19.2.1 fixed my problem
Comment by Stanislav T (stas-t) - Saturday, 12 October 2019, 13:29 GMT
For my case adding "--disable-gpu" to signal-desktop command line was the work-around.
Also when I ran signal with a discrete card (env DRI_PRIME=1 ...) - it didn't freeze, however it doesn't survive laptop suspend.

Today I've found this interesting comment:

That would explain why Slack is working fine but Signal freezes (both are based on Electron). See attached output of flatpak info for both.

Not sure if it's a good practice, but I've opened another ticket:
Comment by Stanislav T (stas-t) - Saturday, 12 October 2019, 18:50 GMT
I think the ticket can be closed. The issue is not related to Arch, it's more about flatpak packaging.
