Hi Roxana, I'm confused by your comment #11. You write about versions 6.5.0-21.21~22.04.1 and 6.5.0-25.25~22.04.1. Do both contain the fix?
As of today, I can see neither of these versions, but only 6.5.0.21.21~22.04.11 (.11, not .1!). And that version has already been released as a regular (not proposed) update. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-hwe-6.5 in Ubuntu. https://bugs.launchpad.net/bugs/2049027 Title: The display becomes frozen after some time when a HDMI device is connected.

[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.

I'd like to ask whether it is possible to apply that patch to the current Ubuntu kernel?
