<pre>X crashes with any configuration on AMD RX590 except ESXi & Xen passthru (works
in Windows 10).
Replacing memcpy with custom impl partially solved the problem.

boots ok but error in amdgpu dmesg (hangs):

signaled seq=2, emitted seq=3

Tested both on current & latest kernels, oibaf drivers don't help.
