Everything worked fine when I first installed Linux last October. I
updated the firmware immediately before installing Linux. I think it
was a couple of months before the boot problems showed up.

I am currently using 4.10. I tried 4.11 yesterday and the keyboard did
not work at all. The error messages changed to:

[    0.453518] ACPI Error: Needed type [Reference], found [Integer] ffff88045bce

Today I ran a regression test to determine which commit made the
keyboard stop working entirely. The last commit that worked for me was
c09e22d5370739e16463c113525df51b5980b1d5. After that, there is a long
series of commits where the screen stays black, and after that, I
start getting errors like the one above.

Thanks for the information you've sent so far. Any ideas on how to fix
this new and serious problem with 4.11?
