Description
It hangs on:
(hal\halx86\acpi\halacpi.c:835) Your machine has a SRAT, but NUMA/HotPlug are not supported!
|
(hal\halx86\acpi\halacpi.c:782) ACPI Timer at: 408h (EXT: 256)
|
(hal\halx86\acpi\halacpi.c:928) ACPI vUnknown_2 detected. Tables: [RSDT] [APIC] [FACP] [SRAT]

It seems TSC calibration fails since it got stuck here:
https://github.com/reactos/reactos/blob/096c0aa9d4ef7e90751e5ab7a07c8661c422e2f3/hal/halx86/apic/tsc.c#L97
while (TscCalibrationPhase < NUM_SAMPLES) _ReadWriteBarrier |
Tried to set HyperV paravirtualized MSR registries for TSC control but it seems to not have effect.
if I skip the TSC calibration, directly reading the HyperV MSR registry (HV_X64_MSR_TSC_FREQUENCY | 0x40000022) for getting TSC frequency, the x64 build goes until it loads videoprt and then hangs. If I delete videoprt, it hangs while kbdclass.sys. If I delete kbdclass.sys, it hangs when loading mouclass.sys. If I delete mouclass.sys, it hangs while loading fs_rec.sys etc.
(Need to try to replace ApicWrite(APIC_EOI,0) with __writemsr(HV_X64_MSR_EOI,0) and __writecr8(Irql) to __writemsr(HV_X64_MSR_TPR,Irql) since HyperV offers a MSR for its virtualized x64 APIC and the EOI is used also for TSC manual calibration that freezes)
