Status in linux package in Ubuntu: Invalid Status in linux-signed-hwe-6.5 package in Ubuntu: Invalid Status in linux source package in Mantic: Fix Released Status in linux-signed-hwe-6.5 source package in Mantic: Invalid Bug description: SRU Justification: [Impact] Multiple users have reported frozen displays when external HDMI device is connected on systems with intel graphics chipsets. [Fix] * backport 49e0a85ec344: "drm/i915/dmc: Don't enable any pipe DMC events" from 6.6.9 [Test Plan] * Tested on Intel TigerLake with iris Xe Graphics and no issues so far. It seems it affects mostly Alder Lake though, but at least it does not cause any issues on other models. * It has also been tested upstream https://gitlab.freedesktop.org/drm/intel/-/issues/8685 [Where problems could occur] * We could see issues on systems with Intel Graphics when HDMI devices are connected during power state changes. Old description: It is exactly this bug: https://gitlab.freedesktop.org/drm/intel/-/issues/8685 It was fixed with that kernel commit: commit 648d7be8ecf47b0556e32550145c70db153b16fb Author: Ville Syrjälä <ville.syrj...@linux.intel.com> Date: Mon Dec 11 23:37:47 2023 +0200 drm/i915/dmc: Don't enable any pipe DMC events https://lore.kernel.org/stable/20231211213750.27109-2-ville.syrj...@linux.intel.com/ which was picked for 6.6.9. I'd like to ask whether it is possible to apply that patch to the current Ubuntu kernel?
