The driver reports

Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff

during initialization.
Comment 1 Alex Deucher 2016-11-21 14:25:06 UTC
This is a message from the pci subsystem, not the driver and it's harmless.  The driver is able to access the rom and load successfully.
Comment 2 Matthias Nagel 2016-11-21 20:10:38 UTC
If it is the pci subsystem where should I report the issue instead?

The error message comes from the drivers/pci/rom.c file. A solution is to change dev_err to dev_info in the pci_get_rom_size function. Amd should manage to make this happen.
