[Bug 1574044] Re: ACPI Error: [\_SB_.PCI0.LPCB.H_EC.CHRG] Namespace lookup failure, AE_NOT_FOUND (20150930/psargs-359)


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:

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

Thanks in advance.
