Public bug reported: Hi,
in lunar (haven't tried others yet), the laptop screen flickers every few minutes, and I get these errors in dmesg when that happens: [qui mai 4 22:07:56 2023] i915 0000:00:02.0: [drm] *ERROR* Fault errors on pipe A: 0x00000080 [qui mai 4 22:07:56 2023] i915 0000:00:02.0: [drm] *ERROR* Fault errors on pipe A: 0x00000080 [qui mai 4 22:07:56 2023] i915 0000:00:02.0: [drm] *ERROR* Fault errors on pipe A: 0x00000080 googling found some hits, but this one seems promising, as it's recent, and has the exact same error message: https://www.spinics.net/lists/intel-gfx/msg317397.html If that is not applied in the lunar kernel, and someone builds me one with the patch applied, I can easily try it.
