Hello,

I've been trying to find out what's wrong myself but couldn't. The APIC 
timer calibration fails in an infinite loop.

I'm running it in bhyve (FreeBSD hypervisor) and according to my tests 
lapic_cal_handler never gets called. This prevents the lapic_cal_loops 
counter from being incremented and therefore the APIC calibration never 
finishes. It is supposed to be called 25 times (APIC_CAL_LOOPS 
constant). I added some apic_printk's to check for these infos (not a 
best practice but I don't have access to a debugger in this specific 
context).

What could cause this ? Is this a known bug ?

Attached are the kernel config and the boot log.

A "stock" Debian kernel boots correctly.

Yours sincerely
