           Summary: rt2500 driver non functional - maybe yenta_socket issue?
           Product: Ubuntu
           Version: unspecified
          Platform: amd64
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: linux
        AssignedTo: fabbione at ubuntu.com

I've been trying to get the opensource rt2500-1.1.0-b2 driver to work on Ubuntu
AMD64.

It works fine on x86_32, as that's what I'm using to type this. The driver fails
to probe the
card correctly because ioremap fails.

The issue appears to be that pci_resource_start() and pci_resource_len() both
return 0. I tried the vanilla 
linux 2.6.11.7 sources, and had the same issue.

I've also removed pretty much everything from the rt2500 code to see what they
were doing. It's pretty much:
pci_enable_device (pPci_Dev);
pci_request_regions(pPci_Dev, print_name)
ioremap(pci_resource_start(pPci_Dev, 0), pci_resource_len(pPci_Dev, 0))

at this point ioremap fails, and the driver stops processing.

>From lspci on x86_32:
0000:02:00.0 Network controller: RaLink Ralink RT2500 802.11 Cardbus Reference
Card (rev 01)
        Subsystem: RaLink: Unknown device 2560
        Flags: bus master, slow devsel, latency 64, IRQ 17
        Memory at 40800000 (32-bit, non-prefetchable) [size=8K]
        Capabilities: [40] Power Management version 2

on amd64:
0000:02:00.0 Network controller: RaLink Ralink RT2500 802.11 Cardbus Reference
Card (rev 01)
        Subsystem: RaLink: Unknown device 2560
        Flags: slow devsel, IRQ 17
        Memory at <ignored> (32-bit, non-prefetchable) [disabled]
        Capabilities: [40] Power Management version 2

If you need anything else, I'll reinstall ubuntu amd64 to test.
