[ 6.255871] xe 0000:00:02.0: [drm] *ERROR* Tile0: GT0: Unsupported GuC v70.20.0! v70.29.2 or newer is required This is also getting a bit involved and noisy to debug on the mailing list, with dmesg attachments and all. Lore is rejecting the messages and they're not getting archived. I suggest filing a bug over at fdo gitlab [1] and continuing there. BR, Jani.
