It appears I'm being added to this thread late. Can you give me some more context?
Which XPS 2-in-1 is this (model number)? And what are the issues?

I'm "guessing" high power consumption over S2I?

If you are trying to debug high power consumption and those patches are causing
problems, can you please remove those patches?

LTR ignoring is an important debugging tactic to find problems with S2I consuming
too much power.

Additionally if you can read /sys/kernel/debug/pmc_core/pch_ip_power_gating_status
That may help to point out what is wrong.
