The problem may be caused by an one-line cleanup code in

dev->class = class;
class >>= 8;
....
/* Early fixups, before probing the BARs */
pci_fixup_device(pci_fixup_early, dev);
- class = dev->class >> 8;
I was thinking the last line is redundant and removed it in that commit,
but apparently the dev->class is changed after the fixup.
Can you please put the line back and try the device again? I'll post a
fix if it works.
Thanks,

Hi,
Just gave that a try and adding that line does indeed fix the problem -
no errors and the controller and DVD are properly detected.
Thanks,
Marc
