Before we do any further investigation, can you please update to the
current 7.1.4-1 in unstable and verify if the problem persists there?

#93506

Hi Harald,

Apologies for the late reply.

On Tue, Jul 21, 2026 at 06:59:39AM +0200, Harald Dunkel wrote:

So given you can reproduce this with a very recent kernel, would you
mind forwarding this to upstream following
https://drm.pages.freedesktop.org/intel-docs/how-to-file-i915-bugs.html
and report the upstream issue filled back here so we can track it?

I think that would be better in this case as if we would forward it,
as you can directly respond to questions from upstream in the filled
issue.

Does that works?

Regards,
Salvatore

#93541 — Re: Bug#1142419: 7.1.3 does not resume "i915 0000:00:02.0: [drm] pipe state doesn't match!"

[Multipart message — attachments visible in raw view] — view raw

Here is my bug entry on freedesktop.org:

	https://gitlab.freedesktop.org/drm/i915/kernel/-/work_items/16740

I could reproduce the problem using upstream's version 7.1.5. Hopefully
it gets a little bit of attention.

Harri
