I went on with investigating that problem and found the problem,
though I'm not sure if that solution is acceptable..
seems like the memory range gets preallocated in setup-bus.c, and
CARDBUS_MEM_SIZE defines that size.
I changed
#define CARDBUS_MEM_SIZE (32*1024*1024)
to
#define CARDBUS_MEM_SIZE (48*1024*1024)
and now the system is able to allocate the resources for the 3rd
pci/pcmcia function.
Can anyone please have a closer look at it too? I think the whole
implementation isn't really good there..
so this is the new output of iomem:
$ cat /proc/iomem
...
30000000-35ffffff : PCI Bus #02
30000000-32ffffff : PCI CardBus #03

3a000000-3affffff : 0000:03:00.1
3b000000-3bffffff : 0000:03:00.2 <- this one failed to allocate previously
3c000000-3effffff : PCI CardBus #07
41000000-43ffffff : PCI CardBus #07
...

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
