           Product: DRI
           Version: DRI git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major

dmesg boot from X550Z

Recent kernel broke the handling of power management for CIK/SI hybrid laptop
using the latest 4.9.25-20170502 from
https://cgit.freedesktop.org/~agd5f/linux/?h=amd-staging-4.9

Notable highlight:

[   25.671428] kfd kfd: Allocated 3944480 bytes on gart for device(1002:130d)
[   25.671449] kfd kfd: error getting iommu info. is the iommu enabled?
[   25.671493] kfd kfd: Error initializing iommuv2 for device (1002:130d)
[   25.671558] Creating topology SYSFS entries
[   25.671642] kfd kfd: device (1002:130d) NOT added due to errors

[  695.257618] [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* displayport

[  695.257654] [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* clock
recovery failed

For a while, suspend/resume will lock up in back screen forcing a hard reset.
Laptop is Asus X500ZE equipped with Kaveri and Hainan dual GPU.

I'm seeing the same *ERROR* lines on suspend/resume on one of my laptops, and
the laptop panel stays black. Does that match your problem, or what did you
mean by "broke the handling of power management"?

For the former, that matches the problem I encountered. 
About the line "broke the handling of power management", I noticed more fan
noise than usual but it may be something else. It will be nice to optimize that
power management if possible.

And you're saying suspend/resume broke around May 2nd for you? Do you happen to
remember a commit before that where it worked for you?

Last commit that worked prior to the breakage was on 20170410. I just updated
to the recent 20170511 which seems partially resolving the issue but the error
message below still remains.

I'm still unclear as to the symptoms you're seeing. E.g., are the *ERROR*
messages always accompanied by a black laptop panel? And does this only happen
on suspend/resume, or also under other circumstances?

Yes, those *ERROR* message happened on suspend/resume followed by the black
screen. Same errors also occurred when leaving the laptop in idle for a while
as well.

The XF86-video-ati driver is probably used. Kaveri does not work with this
driver via DP. I have a black screen too.
