Just got this brand new motherboard with an AMD APU and an AMD chipset.
Whenever I try to boot FreeBSD and AHCI or RAID is enabled in the BIOS, I am
getting this message:
BTX loader 1.00 BTX version is 1.02
int=0000000a err=00000000 efl=00006402 eip=000093e0

BTX halted
It looks like to me the BTX is taking an "Invalid TSS" exception while
executing an iret instruction.
>How-To-Repeat:
I tried: - Booting from the install cdrom
- Booting from an USB install disk
- Booting from boot/pxeboot in PXE mode
All exhibit the same issue.
>Fix:
Selecting "Legacy IDE" mode in the BIOS configuration instead of AHCI/RAID.
