答复: Regression with kernel 4.18 - AMD RX 550 fails IB ring test on power-up

[Qu, Jim]

Hi Luis,

1. May you also test earlier kernel? v4.17 or v4.16.
2. May you test the issue only with amdgpu?

Thanks
JimQu

Hi,

I've tried kernel 4.18-rc2 on a system with a NVIDIA GTX 1050 Ti and an AMD RX 550 4GB and the RX 550 card is failing the IB ring test.

[    5.033217] [drm:gfx_v8_0_ring_test_ib [amdgpu]] *ERROR* amdgpu: ib test failed (scratch(0xC040)=0xFFFFFFFF)

Please see the attached log.
