I recently upgraded my hardware (13600k and MSI B760), and now the hypervisor is refusing to boot. On UEFI it seems to be hanging inside of AllCpusProc when calling UefiToHypervisorTrampoline64. I'm not sure where it's hanging on legacy mode. The only way I've gotten it to boot is by using legacy BIOS configuration and keeping only a single core active in the BIOS.

I've been trying to get this to work for days, but have made no progress due to the erratic behavior I'm seeing. I'm not sure how to debug this or even provide some more information because it's happening long before the OS or hypervisor boots.

lapic id is overflowing and corrupting the stacks of other CPUs, comment this line out, this fix has only been tested on legacy BIOS
