Note that you can't disable mixed mode via a tunable on 5.2.1, so you might want to retest disabling mixed mode. However, the first steps are to work on the non-ACPI case as that is easiest. I'll need 'mptable' output and dmesg output from a verbose boot with APIC enabled and ACPI disabled if you can get that.
