acpi is getting stuck at charging/discharging

[janl]

As I write this I run 4.18.0-12-generic and the ACPI subsystem correctly detects when the powerplug is plugged and unplugged.

In 4.18.0-13 and -14 this does not seem to be the case. The subsystem status will remain as it was when booting if the plug is removed/replaced.

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v5.0-rc7 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.

The issue remains in both mainline 4.20.0 and 5.0.0rc7 generic kernels.

[janl (janl)]

I should perhaps add that then the laptop goes from unpowered to powered the led in the power button does blink. So the firmware stil sennses the power being plugged.

[Kai-Heng Feng (kaihengfeng)]

Please do a kernel bisection between v4.18 to v5.0.

[janl (janl)]

Who do you want to do a bisection?

I wrote that it works in 4.18.0-12-generic and not in 4.18.0-13-generic kernels provided by Ubuntu.

[Kai-Heng Feng (kaihengfeng)]

Commits between each kernel releases are backported from mainline series. It can be easier to find out the regression commit.
