Thanks for the bug report! I have an idea of what could be causing
this, I've cooked a patch, I'm doing a build test. I of course won't be
able to test it as I don't have amdgpu hardware, but I'll share the
patch with you for testing.
Note: I'm not sure where you found <linux-pci@atrey.karlin.mff.cuni.cz>
to be the address of the linux-pci mailing list, it's really
linux-pci@vger.kernel.org.
Best regards,
Thomas
