gnome-shell segfault in radeonsi_dri.so since update to mesa-1:24.0.1

Hello,

Since this package upgraded from mesa-1:23.3.5 to mesa-1:24.0., gdm crashes with a white screen (asking to contact and admin).

No chance to open a gnome session. Reverting package to previous version resolves the issue.

The system journal shows:

févr. 23 16:18:47 linux2 kernel: gnome-shell[1062]: segfault at 40 ip 0000760b622cd545 sp 00007fff20b94be0 error 4 in radeonsi_dri.so[760b61c14000+14dd000] likely on CPU 3 (core 3, socket 0)

So you've already tracked it down, did you search? There's a bunch of threads about this already.

Sorry, I did not pay attention it was already reported.

Re: gnome-shell segfault in radeonsi_dri.so since update to mesa-1:24.0.1

This is solved for WAYLAND by creating, as suggested in the above link, /etc/modprobe.d/amdgpu.conf and /etc/modprobe.d/radeon.conf (the later to blacklist radeon)

Now the amdgpu module is used instead of radeon:

0a:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland PRO [Radeon R7 240/340 / Radeon 520] (rev 87)
	Subsystem: ASUSTeK Computer Inc. Oland PRO [Radeon R7 240/340 / Radeon 520]
	Kernel driver in use: amdgpu
	Kernel modules: radeon, amdgpu

On the other hand, opening a gnome session with X.org produces an error:

[    22.233] (EE) RADEON(0): Failed to initialize surface manager
[    22.233] (EE) Fatal server error:

Xorg should not be trying to load the radeon driver here. Remove xf86-video-ati and get rid of any xorg config still referencing the "ati" driver.

Yes, I was missing xf86-video-amdgpu package.

It is now OK for both wayland and X.org

You don't strictly need that and there have been a few reports that modesetting which would be used in absence of any explicit xf86-video package tends to perform better/have less bugs.
