I can trigger this too with my guest here.

I have these two ontop of rc5:

cc22b9b83f6a x86/irq: Enhance __assign_irq_vector() to rollback in case of failure
45dd79e03e1e x86/irq: Do not reuse struct apic_chip_data.old_domain as temporary buffer
9f9499ae8e64 Linux 4.4-rc5

and my guest stalls while booting.

The new thing I see in dmesg is this:

 ..TIMER: vector=0x30 apic1=0 pin1=2 apic2=-1 pin2=-1
+..MP-BIOS bug: 8254 timer not connected to IO-APIC
+...trying to set up timer (IRQ0) through the 8259A ...
+..... (found apic 0 pin 2) ...
+....... failed.
+...trying to set up timer as Virtual Wire IRQ...
+..... failed.
+...trying to set up timer as ExtINT IRQ...
+..... works.
+APIC calibration not consistent with PM-Timer: 111ms instead of 100ms
+APIC delta adjusted to PM-Timer: 6248393 (6997337)

which leads to boot stalling and timeoutting when loading the hdd
