Description Bruno Pagani 2017-04-04 01:18:07 UTC 
This is a follow-up from https://bugzilla.kernel.org/show_bug.cgi?id=194753.

A lot of recent HP machines shows ACPI Error related to platform specific WMI.

On my system (HP zBook Studio G3), I’ve got this at boot:

You can see several other reports linked in https://bugzilla.kernel.org/show_bug.cgi?id=194753#c5.

Not sure whether this has actual consequences (everything I’ve tried seems to work, excepted for issues with the Nvidia card — https://bugzilla.kernel.org/show_bug.cgi?id=156341), but though it would still be useful to report it.

Please ask for any other information I should provide (there is an acpidump in the other bug).

Another reference
https://bugzilla.kernel.org/show_bug.cgi?id=194671
Looks like a BIOS issue or needs hp wmi developers' attention.
Comment 2 Bruno Pagani 2017-05-13 13:25:30 UTC 
Well it was already part of my listing in https://bugzilla.kernel.org/show_bug.cgi?id=194753#c5. But reaching HP devs seems hard…
