FreeBSD 12.0-RELEASE crashes during the boot process

[Mazandar Wiki]

I'm trying to boot FreeBSD from the installation media
(FreeBSD-12.0-RELEASE-amd64-memstick.img, written on an 8GB USB Flash Drive
by dd(1)). It crashes at the beginning of the boot process, right after
printing this message:

ACPI APIC TABLE:  <GBT              GBTUACPI>

In the verbose mode:
ACPI APIC TABLE:  <GBT              GBTUACPI>
L3 cache ID shift: 4
L2 cache ID shift: 1
L1 cache ID shift: 1
Core ID shift: 1
[crashes here and nothing works, I have to restart by hand]

It sometimes works (and one time, I even managed to install it, though it
didn't work after the first reboot), but most often it crashes. I tried to
disable AHCI in the BIOS, but that didn't work either. Checksums are OK.
Other operating systems (including FreeBSD 9.0-RELEASE) work fine.
