SubjectYenta Cardbus allocation failure
Hi,

I've got a PCMCIA Hybrid TV tuner, but when I plug it in it fails to
allocate resources for the 3rd PCI function.
I already searched with google and someone implemented an otion

parm: override_bios:yenta ignore bios resource allocation (uint

in yenta_socket, though this doesn't seem to work out with that device.

Any idea how that problem can be solved?

So here are some logs
