I followed steps in your reproduce link, didn't reproduce the error as
above line reported. I can still see those PCI_IOMAP warning, however
they will disappear when rebuilding. The clone3 warning can always ben
seen. I didn't see the symbol ioremap error. Could you double check if
anything missed in steps?
