Ok, got it, and managed to reproduce the hang now. My "ARM: pxa/sa1100: move I/O space to PCI_IOBASE" patch managed to get it to the point of detecting the pcmcia device instead of crashing, so I assumed it was enough when it clearly was not. Before that patch, it still works, afterwards it hangs with "pata_pcmcia: probe of 0.0 failed with error -12" as mentioned above. I'll have another look. Arnd
