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 36000000-360003ff : 0000:00:1f.1 39000000-3bffffff : PCI CardBus #03 39000000-39ffffff : 0000:03:00.0 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 ...
