(In reply to Alex Deucher from comment #33) > I think Sonny fixed this. It was due to using the wrong firmware. > [ 1.827060] [drm] initializing kernel modesetting (HAINAN 0x1002:0x6665 > 0x1028:0x0844 0xC3). This chip should be using radeon/banks_k_2_smc.bin smc > firmware. Is that available on the test system and kernel? The firmware radeon/banks_k_2_smc.bin is on the test system. With Ubuntu kernel 4.4.0-101-generic, I am not pretty sure the radeon driver is using this firmware. With Ubuntu kernel 4.13.0-16-generic, I tried both amdgpu and radeon drivers, but the system hang. as soon as the system hang, the amdgpu_pm_info shows 'invalid dpm profile 15'.

(In reply to Alex Deucher from comment #35) > Does reverting a628392cf03e0eef21b345afbb192cbade041741 fix the issue? Removing this commit does not fix the issue. BTW, with 4.13.0-16-generic, I change the max_sclk in drm/radeon/si_dpm.c (what we did with Ubuntu kernel 4.4.0-101-generic) from 75000 to 65000, but still met the hang issue.
