LG 22V240 all in one PC with ACPI problems

[Vicente Jiménez Aguilar]

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.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.6 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Sorry for the delay, this was not my computer but Marta's one.
I'm going to try now latest v4.6 kernel.

[Vicente Jiménez Aguilar (vice)]

Sorry for the delay, this was not my computer but Marta's one.

This computer was bought recently and installed directly with Ubuntu 16.04 in dual boot with Windows.
So no previous kernel version was tested.
Even Ubuntu 16.04 CD install media needed kernel parameter acpi=off to boot.

I just tried kernel 4.6 rc7 and problem persist.
I had also tried upstream kernel version 4.5 with the same results.

Only with acpi=off the system is usable.

Any other option:
Lot of
NMI watchdog: Watchdog detected Hard LOCKUP on cpu 0
other CPU numbers also seen.
System present LightDM after more than 15min.
Desktop not usable due to constant lock-up (detected because mouse pointer and user name input stop blinking)
Does not had the patience to try to log in after waiting more than 20 minutes.

[Vicente Jiménez Aguilar (vice)]

Do I need to run apport-collect with the upstream 4.6 kernel?

I suspect this is a CPU or ACPI table parsing code issue because just with acpi=ht the system is not usable.

[penalvch (penalvch)]

Vicente Jiménez Aguilar, no need to run apport-collect further, unless someone explicitly requests it.

However, could you please test the latest mainline kernel (4.7-rc1) and advise to the results?
