--- Comment #16 from Sylvain Garrigues <sylvain at sylvaingarrigues.com> ---
Guys, I recompiled without CPUTYPE and now the kernel boots. I am so ashamed to
have disturbed you for this.

Though, my CPU *is* Haswell:
# sysctl -a | egrep -i 'hw.machine|hw.ncpu|hw.model'
hw.machine: amd64
hw.model: Intel(R) Xeon(R) CPU E5-2676 v3 @ 2.40GHz
hw.ncpu: 1
hw.machine_arch: amd64

So I'm pissed I can't use CPUTYPE here. Don't know if I should blame KVM or
Amazon. I have another older EC2 machine where CPUTYPE=ivybridge works BTW.

Nevertheless, thanks so much for quick and accurate feedback, you guys are the
reason I wouldn't dream of using any other OS than FreeBSD. THANKS!

Bug can be closed.
