x86/asm works alone

revert of cr4/0 pinning on top of your tree gets stuck as well

Have not yet fully bisected it, but Jiri did and he ended up with

  c522ad0637ca ("ACPICA: Update table load object initialization")

Reverting that on top of your tree makes it work again. Tony has the same
issue.

That still does not explain the cr4/0 issue you have. Can you send me your
.config please?
