suspend fails on Dell XPS 9350

[John Steele Scott]

After upgrading to 5.17.0-1027-oem, my laptop fails to suspend. Instead it turns off.

Journald output:

Upgrading to linux-image-unsigned-6.2.1-060201-generic_6.2.1-060201.202302251141 did not fix the issue.

Nor did rolling back to 5.17.0-1021-oem.

And along the way I found a log file which showed suspend working one time with 5.17.0-1027-oem.

So now I'm not sure what changed to stop this working. :(

Changing the BIOS Fastboot option to "Thorough" seems to have got it working again. Not sure why this would be necessary now.
