It's the first call to this function in si_set_uvd_clocks that's failing.
Doesn't work in bypass mode? Or maybe too low mdelay before call?

[    2.237380] [drm] At call 1
[    3.278457] [drm] At call 2
[    3.288474] [drm] Passed!

Registers dump:
0x634   0x00000706 (1798)
0x638   0x021e0403 (35521539)
0x63c   0x100ece38 (269405752)
0x644   0x00820000 (8519680)
0x648   0x00000000 (0)
