Did previous versions of Linux boot properly on this machine?
Please open a bug report:
https://bugzilla.kernel.org/enter_bug.cgi?product=ACPI
and attach the output from acpidump and dmesg -s64000
from your acpi=off boot.
If you can take a photo of the failed boot, or otherwise
describe it in more detail, that would be helpful.
See if any of these random options help it boot:
acpi=ht (likely this will work)
acpi=rsdt
acpi=noirq
pci=noacpi
thanks,
