Comment # 10
on bug 101946
from Robin
Created attachment 133101 [details] 4.13rc2 ubuntu kern.log Inspecting the output more closely there's a subtle difference in the error produced. While the 4.10 kernel produces: > [ 160.013733] [drm:ci_dpm_enable [amdgpu]] *ERROR* ci_start_dpm failed > [ 160.014134] [drm:amdgpu_device_init [amdgpu]] *ERROR* hw_init of IP block <amdgpu_powerplay> failed -22 The 4.13rc2, drm-next-4.14-wip and drm-next-4.14-wip with patch 3 produce: > [ 134.226312] [drm:cik_sdma_ring_test_ring [amdgpu]] *ERROR* amdgpu: ring 9 test failed (0xCAFEDEAD) > [ 134.226822] [drm:amdgpu_device_init [amdgpu]] *ERROR* hw_init of IP block <cik_sdma> failed -22 And something I noticed for the third bind error cases, the 2nd and 3rd time have much longer ring 1 tests than the first bind. > [ 69.938959] [drm] ring test on 1 succeeded in 2 usecs > ... > [ 102.040253] [drm] ring test on 1 succeeded in 677 usecs > ... > [ 134.121468] [drm] ring test on 1 succeeded in 677 usecs
