Interesting.

For the record, I don't mind running with acpi=off, but it's very weird to
me that new kernels suddenly stopped working without it.

From the fact that I maintain my own kernel builds, you may infer how much faith I put in distro supplied kernels (any distro, not singling any specific distro out).

Thanks. I actually need to test with as new of a version as I can because I
have been experiencing an occasional "page allocation failure" kernel panic.
No idea if/when that was fixed but I figure the newest version is my best
hope.

I've been on my own 4.9.x more or less since I got the machine, it was in 24/7 use, and I never experienced that issue. So it may be worth a cross-check with the kernel that I'm running to see whether the fault follows your machine or whether it is kernel dependent.
