Hello, I have a supermicro server with motherboard H8DMR-i2 v2.0 (http://www.supermicro.com/aplus/motherboard/opteron2000/mcp55/h8dmr-i2.cfm)
The bios is at the latest level and I have 2 - 6core AMD CPUs.
I've been running FreeBSD 9.3 with ZFS on root. When upgrading to 10.0 using freebsd-update -r 10.1-RELEASE. The upgrade completes but the system halts on reboot:
BTX loader 1.00 BTX version is 1.02
Consoles: internal video/keyboard
BIOS drive A: is disk8
BIOS drive C: is disk9

After the POST, the "spinning cursor" appears for just a second or two before it halts.
I did a fresh 10.1 install on a new disk (same server) and the same thing happened. I also tried 10.2 beta (FreeBSD-10.2-PRERELEASE-amd64-20150704-r285132-memstick.img) with the same result.
The system works fine on 9.3/zfs as well as 10.x/ufs. The problem only seems to occur on 10.x.
I booted using a 10.1 installer memstick and went to a shell. I can import the ZFS "zroot" pool. I verified that the /boot/ directory contents of this pool matched the install memstick /boot/ (except kernel symbols files are not on the installer).
Can someone please advise on next steps to resolve? I have a number of these systems and I would very much like to run 10.x.
It does boot and run OK using FreeBSD-11.0-CURRENT-amd64-20150625-r284814.
Updated: Same problem occurs using 10.2-BETA2
I was able to identify the cause of the problem.
There is a BIOS setting WHEA (Windows Hardware Error Architecture) under the ACPI mode section. If set to ENABLED, the system will BTX HALT as above. If WHEA is set to DISABLED, the system boots and runs fine.
If you set the BIOS settings to "Optimal" it will enable WHEA among other things. I used the the Optimal settings and then set WHEA to DISABLED. The setting is under BIOS / Advanced / BIOS features / ACPI Mode / General WHEA configuration / (choose Enabled or Disabled).
Since it worked fine on 9.x and 11.x, can it be fixed in the BTX loader for 10.x?

Hi, same problem here (10.x fails, 11 ok), adding information in case it's useful for debugging.
I'm running it on Asus M2N-MX bios 1004. On ACPI options I can choose between v1, v2 and v3. On v3 I get the BTX halted error, but boots ok otherwise. I'm attaching dmesg for 10.1 and ACPI v3.
Just tested on 10.2-RC1. Same failure.
It would be a nasty surprise to anyone with this machine type when upgrading from 9.x to 10.2 and not being able to boot after freebsd-update if they don't know about the bios setting.
