Description Ehsan 2016-05-05 23:08:28 UTC

On "Dell Inc. XPS 8900/0XJ8C4" with "i7-6700 CPU @ 3.40GHz (family: 0x6, model: 0x5e,
stepping: 0x3)"

I get this error:

Comment 4 Lv Zheng 2016-05-10 00:41:27 UTC

Decoding the DSDT, I got:
    If (LEqual (PCHV (), SPTH))
    {
        Scope (_SB.PCI0.XHC.RHUB)
        {
            Device (HS11)
            {
                Name (_ADR, 0x0B)  // _ADR: Address
            }

            Device (HS12)
            {
                Name (_ADR, 0x0C)  // _ADR: Address
            }

            Device (HS13)
            {
                Name (_ADR, 0x0D)  // _ADR: Address
            }

            Device (HS14)
            {
                Name (_ADR, 0x0E)  // _ADR: Address
            }

            Device (SS07)
            {
                Method (_ADR, 0, NotSerialized)  // _ADR: Address
                {
                    Return (Add (SSPA (), 0x06))
                }
            }

            Device (SS08)
            {
                Method (_ADR, 0, NotSerialized)  // _ADR: Address
                {
                    Return (Add (SSPA (), 0x07))
                }
            }

            Device (SS09)
            {
                Method (_ADR, 0, NotSerialized)  // _ADR: Address
                {
                    Return (Add (SSPA (), 0x08))
                }
            }

            Device (SS10)
            {
                Method (_ADR, 0, NotSerialized)  // _ADR: Address
                {
                    Return (Add (SSPA (), 0x09))
                }
            }
        }
    }
Decoding the SSDT7, I got:
    Scope (\_SB.PCI0.XHC.RHUB.HS11)
    {
        Method (_UPC, 0, NotSerialized)  // _UPC: USB Port Capabilities
        {
            Return (GUPC (One))
        }

        Method (_PLD, 0, NotSerialized)  // _PLD: Physical Location of Device
        {
            Return (GPLD (Zero, 0x0B))
        }
    }

The problem happens when the ACPICA interpreter is trying to load the SSDT.

So this is the known module level code support issue.
This module level support could be fixed by just moving module level execution to per-table basis, thus this should have already been fixed by an upstream module level support improvement.

Could you try this tree:
https://git.kernel.org/cgit/linux/kernel/git/rafael/linux-pm.git/log/?h=linux-next

# git clone git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git
# git checkout linux-next

And try again.
It is fixed by this improvement:
https://git.kernel.org/cgit/linux/kernel/git/rafael/linux-pm.git/commit/?h=linux-next&id=3d4b7ae9

Thanks and best regards

Comment 6 Ehsan 2016-05-11 18:12:16 UTC

Ok I ran from 30547a50d21433fcc680edaf5a492f17533618ee.
I no longer see ACPI errors

However, now I have to use nomodeset to be able to boot otherwise the monitor turns off. Even if I select other kernels, or even use a LiveCD now I need nomodeset! How is that possible? 
First time after booting the new kernel, I think I saw something about firmware being updated! I updated my BIOS again to see if that could help, but it did not solve the problem with the need to use `nomodeset` now. It is NVIDIA graphics, but it worked on previous kernels, now even those kernels I need the kernel switch which uses software rendering.

Attached is the new acpi dump.

Created attachment 215941 [details]
New ACPI dump

New ACPI dump after booting new kernel (but with nomodeset)

There is just one warning:

Looks like the same issue.
You can also try this tree:
https://git.kernel.org/cgit/linux/kernel/git/rafael/linux-pm.git/log/?h=linux-next

# git clone git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git
# git checkout linux-next

This is a different issue.
You can file a different bug entry tracking this if you want.

I compared the 2 tables, and did saw changes in BGRT.
Looks like this is related to the new issue.

Comment 12 Lv Zheng 2016-06-02 03:12:49 UTC

Ping Ehsan:

The problem you reported seems to be an un-root-caused regression (it need to be in upstream if it is a regression) while the bug of the errors should have been fixed.

Now the fix is already in the upstream via ACPICA release.
Could you try the recent linus tree to see if the issue persists:
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

If it is there, please upload the boot log here for tracking.
You could also file another regression report for the new issue.

Thanks and best regards

Let me close because of no response.

You can re-open it when you encounter new issues.

Comment 14 Ehsan 2016-06-29 03:46:29 UTC

Sorry for late reply! Yes it is fixed on the latest kernel,thanks!

Comment 15 Tomáš Pružina 2017-07-27 13:06:48 UTC

Had the same issue on my Z170 board, got fixed after manually applying the patch (which still isn't in Linuses tree). Did this merely got lost from pipeline or have some regressions appeared?
