Cannot boot Linux kernel on a new laptop Acer Nitro AN515-51 without acpi=off.


Tests on (then) upstream kernel (4.15.0-041500rc1-generic using ukuu tool):
<none>: reboots
acpi=off: works without ACPI info
acpi=ht: reboots
pci=noacpi: freezes after kernel loading
acpi=noirq: freezes after kernel loading
pnpacpi=off: freezes after kernel loading
noapic: reboots
nolapic: boots, shows kernel messages and then freezes

Launchpad bug report:

Since there is no info in sysfs, `sudo fwts acpidump` info is here:

dmidecode output is in attachment.

If needed, I can test.
