Can you please test with master?

FYI at least some of these are fixed by: https://github.com/torvalds/linux/commit/5a8361f7ecceaed64b4064000d16cb703462be49

Thank you. The system is used by a user in production now, so I do not have the means to test this anymore. Could Dell provide a test system to the Intel folks?

OK.  That's unfortunate you can't further verify.

> Could Dell provide a test system to the Intel folks?

Intel can request hardware from Dell through normal business channels if it is needed.  A bug report is not an appropriate channel for this.
Comment 4 Zhang Rui 2018-05-02 03:30:19 UTC 
I think we have a Dell 9370 that I can remote access.
As the ACPICA changes referred above has been shipped upstream, I will check if the problem is gone in latest upstream kernel.

I was able to get my hands on that device again, and confirm, the ACPI errors are gone.

Hi,

I also have the same machine. I just tried 4.17 rc5 and can confirm that the errors are gone from boot. However there are more ACPI errors in the log at a later point:

Thank you for you comment, but please always create a new ticket for issues not covered in the original comment. Though I am aware, that the subject/title is quite general. Anyway, in your cause, I believe it’s covered by bug #199557 [1].
