Public bug reported:
I have the following problem with a LG all in one PC V220.
Ubuntu 16.04 does not boots unless ACPI is deactivated with acpi=off kernel
option.
Never see the X starting after waiting a lot of minutes.
Removing the quiet kernel parameter we can see the kernel reporting a lot of
errors and progressing very slowly.
None of those parameters allowed a normal boot:
acpi=ht
pci=noacpi
acpi=noirq
pnpacpi=off
noapic
nolapic
Only acpi=off allowed the system to boot.
But with very poor performance and only one core CPU.
Tested also latest vanilla linux kernel with same problem.
Hardware information in attached files.
Attached ACPI dump extracted from Windows.
I have some experience with many GNU/Linux distros but no experience debugging
ACPI.
I am willing to help debug this issue.
Tell what you need.
