            Bug ID: 92836
           Summary: amdgpu does not resume properly from suspend
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: David@WalkerStreet.info

My laptop does not resume properly after a suspend.  The problem seems to be
with the amdgpu kernel module; it's often accompanied by a long stream of dmesg
errors reported.  Here's a sampling:

 [ 1494.980561] amdgpu 0000:00:01.0: GPU fault detected: 146 0x0b020504

Any ideas?  I'm running the 4.2.4-1-default under openSUSE Tumbleweed.  Here's
some hwinfo data:

I've attached dmesg and Xorg.0.log files for 4.3.0-1.g7b374a4.  It appears that
the GPU faults have gone away, but the visual symptom is still the same; the
screen is blank after a resume.

You'll also note that there are a *lot* of "xhci_hcd 0000:00:10.0: WARN
Successful completion on short TX" messages in the dmesg output.  I suspect
they're unrelated, but they don't appear under 4.2.3-1.4.

Does booting with apci_osi=Linux on the kernel command line help?  A lot of new
laptops use d3cold to support windows 10 which Linux in general doesn't support
at the moment.

apci_osi=Linux doesn't seem to help.  I have found that it does recover
sometimes, albeit rarely, and more often when running Gnome with Wayland,
rather than X11, and sometimes only after control-alt-backspace.  I haven't
done all that much testing, though, so this all may simply be coincidence.

Any other debugging I could do?

Over the past couple of Tumbleweed kernel upgrades (most recently
kernel-default-4.3.0-6.1.g6b3b033), I've noticed that resumes succeed
sometimes, and that if a resume fails, another one or two suspend/resume cycles
will result in a successful resume. FYI, I'm also using
ucode-amd-20151109git-35.1 and kernel-firmware-20151109git-35.1.

I have attached Xorg.0.log and the following three "dmesg -c" outputs:

  suspend1.dmesg - before any suspends
  suspend2.dmesg - after two suspends, the first of which failed
  suspend3.dmesg - after one suspend that succeeded

David, can you try newer kernel? I get the same errors with Fedora kernel 4.5.4
on

01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.
[AMD/ATI] Tonga XT / Amethyst XT [Radeon R9 380X / R9 M295X] [1002:6938] (rev
f1)

but the errors are non-fatal, i.e. there is graphics corruption but no hangs.
Restarting X removes graphics corruption.

Sorry, Vendran, but I ended up buying another laptop (this time from a company
that specializes in Linux laptops), so I no longer have a testbed for this.
