  acpi is getting stuck at charging/discharging

Status in Linux:

Status in linux package in Ubuntu:

Bug description:
  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.

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.

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.

[Kernel-packages] [Bug 1814539] Re: acpi is getting stuck at charging/discharging

2019-02-18 Thread Kai-Heng Feng
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.

Title:
  acpi is getting stuck at charging/discharging

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  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.
