"random" hangs during boot, ACPI related ? Workaround problem by disabling HTT

Hello list,

I've had a problem a couple of times now that I wanted to share with
the list to see what you have to say. The problem is that FreeBSD
sometimes hangs during boot, the last line of output from the kernel
is "ACPI APIC Table: <INTEL  DENLOW>" and then nothing more happens.

This seems to be related to something not getting initialized correctly
after a soft reboot, but only sometimes. The first time I tried this it
was on
a server that has been in production for months, and suddently after a
reboot during an installworld run it froze. Even a verbose boot doesn't
reveal anything that jumps at me: http://i.imgur.com/y04ACyP.png

Hard rebooting the server appears to solve it, until next reboot where
it may or may not happen again.

The same problem seems to affect others. This is the thread where I
found suggestions for workarounds: https://bugs.pcbsd.org/issues/4024

Workarounds include disabling C3 or disabling HTT in bios. Disabling C3
did nothing for me, but disabling HTT made the server boot successfully
again.

The FreeBSD versions involved are 9 and 10, various versions. I've
attached /var/run/dmesg.boot from one of the servers that had the
problem a few weeks ago. On this server I've disabled HTT in the bios
which worked around the problem.

I just bought a new server at Hetzner (the hosting provider where I am
experienzing this problem) and the server is not in production yet. I
wanted to hold off on disabling HTT to see if anyone wants me to
check something so we can get this fixed.

Thoughts ? More info available on request.

Best regards,

/Thomas Steen Rasmussen
