From: "Chia-Lin Kao (AceLan)" <acelan.kao@canonical.com> BugLink: https://bugs.launchpad.net/bugs/2067883 [Impact] The i915 doesn't load and got below message Jun 03 04:23:16 kernel: i915 0000:00:02.0: Your graphics device 7dd5 is not properly supported by i915 in this kernel version. To force driver probe anyway, use i915.force_probe=7dd5 module parameter or CONFIG_DRM_I915_FORCE_PROBE=7dd5 configuration option, or (recommended) check for kernel updates. [Fix] Applied below commit fixes the issue 213c43676beb drm/i915/mtl: Remove the 'force_probe' requirement for Meteor Lake [Test] 1. boot up mtl system 2. see if the graphics works normal [Where problems could occur] We have been using 6.5-oem kernel for quite a long time to support mtl platforms. So far, we don't see any i915 gfx related issues. So, it should be safe to remove mtl force_probe on 6.5-hwe kernel.
