Public bug reported:
Hello,
I am experiencing a suspend/resume failure on Ubuntu 26.04.1 LTS, on a
Dell XPS 13 9315.
Hardware and software
Laptop: Dell XPS 13 9315
CPU: Intel Core i7-1260U
Graphics: Intel Iris Xe, driver i915
BIOS: 1.41.0
Ubuntu: 26.04.1 LTS (Resolute)
Kernel versions tested: 7.0.0-38-generic, 7.0.0-31-generic, and
6.14.0-1019-oem
Problem
When I suspend the laptop, either by closing the lid or selecting Suspend, the
screen remains black when I try to resume. I have to force a shutdown using the
power button.
The problem occurs with all three kernel versions listed above.
The previous boot's kernel log ends with:
PM: suspend entry (s2idle)
I also see the following messages in the kernel log:
i915 ... Selective fetch area calculation failed in pipe A
intel-ipu6: IPU6 bridge init failed
I understand that these messages may not be the cause of the suspend
problem.
Could this be related to a kernel suspend/resume regression? Please
advise on how to collect any additional diagnostics needed.
Thank you.
