Created attachment 126300 [details] kernel log tested on drm-next-4.9-wip: 1) 832c6ef + 2 patches from Tom and Michel (another bugs) 2) 2c0d731 the same behavior on both. With dpm=0 amdgpu doesn't complain and works with intel. Hard to say it's regression because when I tried DRI_PRIME few month ago dpm didn't work at all.
Created attachment 126508 [details] dmesg log with latest drm-next-4.9-wip: 72bb0f5 modprobe -r amdgpu: at "148 modprobe amdgpu: at "162 It's some kind of progress, because intel-gfx works but amdgpu doesn't start at all. error from dmesg looks like the same: https://bugs.freedesktop.org/show_bug.cgi?id=97801 kernel: drm-next-4.9-wip: 72bb0f5
probably a duplicate of bug 97801
Created attachment 126519 [details] dmesg log with latest drm-next-4.9-wip: 97231a9 unfortunately it doesn't when bug 97801 is solved now, kernel log looks like similar for the first log [ 90.544035] amdgpu 0000:01:00.0: fb1: amdgpudrmfb frame buffer device [drm:gfx_v6_0_ring_test_ib [amdgpu]] *ERROR* amdgpu: IB test timed out [drm:amdgpu_ib_ring_tests [amdgpu]] *ERROR* amdgpu: failed testing IB on GFX ring (-110).

For new drm-next-4.9-wip and drm-next-4.9 symptoms are the same as before.
I've just tried newest drm-next-4.9-wip: 1c22b05623e5e03ada5a767951eac3203b246be9 and there is something new in kernel log: [ 3430.379659] amdgpu 0000:01:00.0: fb1: amdgpudrmfb frame buffer device [ 3431.438851] [drm:gfx_v6_0_ring_test_ib] *ERROR* amdgpu: IB test timed out [ 3431.438862] [drm:amdgpu_ib_ring_tests] *ERROR* amdgpu: failed testing IB on GFX ring (-110).

Created attachment 127149 [details] full dmesg for next-drm-4.9-wip: 1c22b05
This is reproductible on kernel 4.9-rc7 even with the branch drm-fixes-4.9 from agd5f repository merged https://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-fixes-4.9 The branch was pointing on bcfdd5d5105087e6f33dfeb08a1ca6b2c0287b61 when I merged it. I can use amdgpu with dpm=0 but performance is bad (not surprising for an experimental support on southern island). I would like to bisect but the dpm never worked on amdgpu SI as far as I know.
I don't have HW (multiGPU) to test it anymore, so fill free to close it in any time/way you want.
I was still getting issues with amdgpu when I tested linux 4.9 + merge from drm-next 4.10 but the dmesg changed (another error code). Will try another merge in next days and post the new error codes.
