--- Comment #30 from David Nichols (david at qore.org) ---
The amdgpu problems in my system were completely and definitively resolved with
a memcpy() patch to glibc:
https://gist.github.com/jnettlet/f6f8b49bb7c731255c46f541f875f436

The SoC I'm using (NXP LX2160A - SolidRun HoneyComb system) has a known bug
regarding PCI device memory writes that can be completely addressed with a
simple reordering of the assembly instructions in the arch-specific memcpy()
implementation. 

In any case, this is not a kernel bug for me after all.  I can't comment on the
source of the problem for others who most likely are running an x86_64 kernel.
