Error1

Processor: E5-2650L V3
No Raidcard installed
BIOS: UEFI Mode
Firmware: all up to date
Version FreeBSD 12.1

Issue:
When trying to install FreeBSD12.1 with X2APIC enabled in BIOS, the kernel gets
in a mess and hangs

With X2Apic turned off the OS boots just fine. However with X2APIC turned off I
loose Hyper Threading abilities.

I've tried the following tunables.

kern.cam.boot_delay="10000"
vfs.root_mount_always_wait=1

Neither work.

Misc:
Debian boots fine

OmniOS fails with: 
No SOF interrupts have been received this USB ehci host-controller is unusable
