--- Comment #13 from Vadim Yanitskiy (vyanitskiy at sysmocom.de) ---
Here we go:

[  582.721066] amdgpu: iceland_populate_all_memory_levels(): mclk_table has 3
entries
[  582.721081] amdgpu: iceland_populate_all_memory_levels(): dpm_levels[0] is
30000
[  582.721095] amdgpu: iceland_populate_all_memory_levels(): dpm_levels[1] is
60000
[  582.721110] amdgpu: iceland_populate_all_memory_levels(): dpm_levels[2] is
90000
[  582.722669] amdgpu: VBIOS did not find boot engine clock value (29900) in
dependency table. Using Memory DPM level 0!

As can be seen, the driver falls-back to level 0, which is very close to the
requested value (29900 vs 30000).  Looks like a bug in VBIOS, because AFAIU,
value 29900 comes from there (see smu7_dpm_patch_boot_state() in
'drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c').  In any case, this does
not look critical to me too.

Best regards,
Vadim.
