With a recent benh kernel I get this message on card insertion:
cs: unable to map card memory!
This seems to be caused by changes to the pci code. In the old kernel
(2.4.4-pre3) I have this in /proc/iomem:
80081000-80081fff : usb-ohci
80082000-80082fff : usb-ohci
a0000000-a0003fff : aty128fb MMIO
a4000000-a7ffffff : aty128fb FB
With the new kernel (2.4.6-pre8) I get this:
80000000-9fffffff : /pci at f2000000
80000000-8007ffff : Apple Computer Inc. KeyLargo Mac I/O
80080000-80080fff : Texas Instruments PCI1211
80081000-80081fff : Apple Computer Inc. KeyLargo USB (#2)
80081000-80081fff : usb-ohci
80082000-80082fff : Apple Computer Inc. KeyLargo USB
80082000-80082fff : usb-ohci
80400000-807fffff : PCI CardBus #02
a0000000-afffffff : /pci at f0000000
a0000000-a0003fff : ATI Technologies Inc Mobility M3 AGP 2x
a0000000-a0003fff : aty128fb MMIO
a4000000-a7ffffff : ATI Technologies Inc Mobility M3 AGP 2x
a4000000-a7ffffff : aty128fb FB
f1000000-f1ffffff : /pci at f0000000
f3000000-f3ffffff : /pci at f2000000
f3000000-f33fffff : PCI CardBus #02
f5000000-f5ffffff : /pci at f4000000
f5000000-f5000fff : Apple Computer Inc. UniNorth FireWire
f5200000-f53fffff : Apple Computer Inc. UniNorth GMAC
The attached patch fixes things for me. It uses the check_region/
check_mem_region in the pcmcia code which descents the resource
tree instead of check_resource which does not.
