On the Intel Kaby Lake laptop Dell XPS 13 9360, at least Linux
6.13.0-07632-gaa22f4da2a46 logs the new warnings:

(Just a side note, these are actually logged with level error.)

rtsx_pci 0000:3b:00.0: Unable to change power state from D0 to D3hot, device inaccessible
rtsx_pci 0000:3b:00.0: PM: dpm_run_callback(): pci_pm_resume returns -110
rtsx_pci 0000:3b:00.0: PM: failed to resume async: error -110

These were not present up to including Linux 6.13.0-07078-gb46c89c08f41.
...

Please try if this fix helps:

Yes, after applying the patch these errors were *not* logged in three ACPI
S3 suspend/resume cycles.

Thanks, I added your Reported-by to the patch, which should appear in
v6.14-rc2. Happy to also add your Tested-by if you feel confident
enough.

Sure.

Tested-by: Paul Menzel <pmenzel@xxxxxxxxxxxxx> # Dell XPS 13 9360


Kind regards,
