I've just installed 6.0-RELEASE again.
I booted it using [default] option (e.g. with ACPI enabled)
and installation ran smoothly. However, I could not extract
/usr/ports/distfiles/gettext-0.14.5.tar.gz, /usr/ports is mounted
from 4.11 installation. All disk activity stopped and kernel
repeatedly wrote something about "DANGER Will Robinson !!",
I think it was from /usr/src/sys/dev/ata/ata-queue.c
I rebooted with ACPI disabled and the problem disappeared.
Now I'm going to test 'debug.acpi.disabled="pci_link"' case.
