This patch on linux-next causes a great amount of:
X xxx.xxxxxx Emulated RAZ for ID register: ISS 0x36002f
messages printed by the system firmware on the Qualcomm SM8550 SoC,
and the platform is barely usable.
As others have said on this thread, this is a firmware bug.
Not a lot we can do about that, unfortunately, apart from hiding
the new feature behind a config option that you'd disable on this
platform.
Alternatively, disabling idle management on this machine should
reduce the screaming greatly.
I have informed Carl about the Gunyah messaging, I have also added him
into this thread.
