Well, its booting, but stops after configuring lo0.  Try hitting
    ^T there instead of escaping into the debugger and see if it tells
    you what command it is trying to run.

I've tried patches from http://bugs.dragonflybsd.org/issue1267 with no luck.
Also, system not responds to ^T.

From the dmesg, it is not related.

May be you should try 'ps' in ddb?

Results of ps in enclosed file.

Very odd.  It doesn't look like a hang to me, it looks like fsck might
    be running on ad6, which is a 1TB drive.  It should be possible to ^C
    it.  A fsck on a huge UFS partition can take hours.

If you have physical access to the box, can you see if the drive light
    continues to show activity after the machine has hung (and not dropping
    into ddb)?

If it can boot that far you should be able to boot -s to get into single
    user mode and mess around from there... maybe run the fsck's manually
    to determine if an actual lockup is occuring or whether it is simply
    a long-running fsck.

Well, HDD LED is not lights, 1Tb hard drive is empty (I mean no partitions), I
can boot system with non-ACPI kernel. It is definitely not a long-running fsck.

Ah, ok.  Well, if you can run with SMP and without ACPI then that is 
   how you are going to have to do it.  We have always had issues with ACPI
   on certain BIOSes.

Most issues with newer Intel motherboard is resolved with importing of newpci and
polishing MADT code.
