Created attachment 305855 [details] dmesg Updating Linux kernel to 6.7.0 brings an issue with build in display. Product: ROG Zephyrus GA502IV Video: VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Renoir [Radeon RX Vega 6 (Ryzen 4000/5000 Mobile Series)] (rev c6) How to reproduce: - update to kernel 6.7.0 - reboot How to fix: - install 6.6.X kernel - reboot Tested kernels that work: - Fedora 6.6.X - ArchLinux mainline kernel 6.6.X - G14 kernel 6.6.X - LQX kernel 6.6.X - XanMod kernel 6.6.X Updating any of the mentioned kernel to 6.7 does reproduce this bug. Also found the same issue on Fedora forum https://discussion.fedoraproject.org/t/update-resulting-in-corrupted-or-garbled-video-on-zephyrus-display/103388/3 And in Discord's g14 bug report https://discord.com/channels/725125934759411753/1194725185807450213 Unfortunately I can't find an option to add a photo. But fedora link has an example how it looks like.

If that's the case you are on your own. If not, you want to report the problem here: https://gitlab.freedesktop.org/drm/amd/-/issues ; in that case please drop a link here.

But to make sure that this is not Nvidia related bug, I disabled nvidia driver and than even uninstalled dkms modules and packages. I was struggling where to open this bug, here or in drm/amd issues, decided to open here because it doesn't look like admgpu bug, I switch the kernel to reproduce the issue, I don't change admgpu driver's version. Are you sure I need to move it to drm/adm?
(In reply to Alexei from comment #2) > I switch the kernel to > reproduce the issue, I don't change admgpu driver's version You did not change mesa's amdgpu driver, but if you switched the kernel, then you are running a different "version" of the kernel's amdgpu driver :-) That being said: https://gitlab.freedesktop.org/drm/amd/-/issues might nevertheless turn out to be the the wrong place; but given the current state of things it's the best place to report this.
