Dear Linux folks,
Just a heads-up, on the Dell XPS 13 9315 over half a second during boot
seem to be due to delays in firmware provided ACPI/ASL.

I created two bug reports [1][2] for each of these delays.
Unfortunately, the device is used in production by a user, so I can’t do
any testing.
Linux taking less than 0.5 seconds to execute on modern consumer
hardware still should be a goal in my opinion.
Kind regards,
Paul
