Thanks for confirmation. The test of the second kernel isn't needed.

It's likely the issue Boris reported recently on ML. I'll add info there.

Unless the fix appears shortly, I'll revert the affecting patch for TW. You can keep using my test kernel until we revert or fix on TW kernel.

I forgot to mention this strange issue I noticed while testing. When you run with "nomodeset" red looks blue etc. false colours appear on X11. I don't know if it is related to anything but I thought I better share. Thank you again. -- You are receiving this mail because: You are the assignee for the bug.

It's still unresolved in the upstream side, and the development will be paused for a while due to vacation, I'll revert the buggy patch as a temporary workaround for TW kernel.

Let's keep this bug open until we receive more proper fix from the upstream.

On Reddit I saw another user updating to 6.8.9 kernel and his/her issue was fixed. I booted to openSUSE TW with 'nomodeset' and did 'zypper dup' to get all updates including 6.9.1 . System freezes during boot process right after nouveau module mentioned. I booted with nomodeset to X11 and made sure machine is connected. Once I issue 'modprobe nouveau modeset=1' command, system freezes and unfortunately I can't ssh to it (no route to host). -- You are receiving this mail because: You are the assignee for the bug.

Now we identify a place that may cause a memory corruption, and this *might* be the culprit of your problem: https://lore.kernel.org/r/20230814144933.3956959-1-kherbst@redhat.com

I'm building yet another test kernel with the fix (and the drop of the previous revert) in OBS home:tiwai:bsc1214073-4 repo. Could you test the kernel later and report back?

I am currently on your build it runs perfectly with both wayland/x11 I even did run glmark2 . When I wanted to make sure openGL is working etc, I have installed/run flatpak io.github.arunsivaramanneo.GPUViewer which just calls gl information from system and shows in a formatted view. GPU freezes that time with a lot of messages regarding nouveau. I am not sure if there is a co-incidence or related to this issue. -- You are receiving this mail because: You are the assignee for the bug.
