Both systems run amd64. I'll try the tunable when I get back home.
Thanks!

Nope. The MacBook does use Apple's Boot Camp, but I can't say whether
that can be considered to be a hypervisor. What happens, is that the
system just locks up after probing all the device. It doesn't mount
the
root device anymore.
Hmm, I think Boot Camp is not hypervisor, and should be treated as
real hardware. Which architecture (i386/amd64) you are using?
(2) On both system, is there no problem before this commit?
I bisected it and the revision before this one does boot. I'll
experiment with the tunables this afternoon. I really had to get some
sleep last night, so I couldn't investigate it any further.
You can try with hw.clflush_disable="1" in loader.conf. If you can
boot with it, I must be mistaken something (anyway its my fault).
Can you show me CPUID line at boot message (of course from the kernel
you can boot) like this?
