I was looking for differences between my old 5.x kernel and the new one, and realized I left 'device apic' in my new kernel. Rebuilding without it makes everything work fine.

Thanks to the couple folks who tried to help with this, even on a holiday. -David -- "What's the good of having mastery over cosmic balance and knowing the secrets of fate if you can't blow something up?" -Terry Pratchett
