Loader hangs on the latest -STABLE

[Igor Pokrovsky]

Hello all,

I haven’t been using FreeBSD since 8-STABLE times. Recently I tried to install latest 12-STABLE on my old computer.
But even during initial boot up loader hangs. Eventually I was able to proceed with installation after replacing loader in 
the installation disk with one found in my old system 8-STABLE. The same happened when I tried zfs on root partition.

I used MBR partition on PATA hard drive. Motherboard was ASUS A8V (Athlon64).
