https://bugzilla.kernel.org/show_bug.cgi?id=215003 --- Comment #7 from Lukas Wunner (lukas@xxxxxxxxx) --- The gpu-switch utility I've linked to above has macOS and Windows versions. You could try using it from one of those OSes to switch to the iGPU on next boot, then boot into Linux. Perhaps you could add a few debug printk's to find out which runtime services call causes the crash. In summary, there are two issues here: The EFI issue which prevents you from switching to the iGPU on Linux, and the GMUX incompatibility. You may want to open a separate bug for the former and assign it to the "EFI" Product so that Ard Biesheuvel and others can take a look. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
