--- Comment #4 from emersion <contact at emersion.fr> ---
This error:

    (kms_chamelium:2874) CRITICAL: Failed assertion: wait_for_hotplug(mon,
&timeout)
Subtest common-hpd-after-suspend failed.

is a duplicate of: https://bugs.freedesktop.org/show_bug.cgi?id=111045

However, this one:

    <3> [322.005537] [drm:intel_display_resume [i915]] *ERROR* Restoring old
state failed with -22

seems like a kernel issue.

User impact: I'm not sure what the exact implications are, but the worst case
scenario is a black screen after resume on a monitor connected via USB-C.

Reproduction rate: weekly, but this issue doesn't happen all the time.
