There is a big progress. Laptop can now successfully suspend (S3) and resume many times in a row. _Thank you very much for your hard work_. But unfortunately hibernate to disk (S4) still does not work as expected. Process is causing hard lockup (system freeze) just on the first attempt. Display goes black (backlight is on), cpu is getting hot (fans are working 100% rpms), and I can do noting more than press "power button" to hard reset the machine. There is no more "amdgpu_atombios_dp_link_train" message in dmesg instead there are mesages related to "swiotlb buffer is full" and "swiotlb: coherent allocation failed" as in the bug: <a class="bz_bug_link bz_status_NEW " title="NEW - amdgpu 0000:07:00.0: swiotlb buffer is full (sz: 2097152 bytes)" href="show_bug.cgi?id=104082">https://bugs.freedesktop.org/show_bug.cgi?id=104082</a>.
