Can't use rt2x00-drivers: PCI request regions failed

Hello,

I can't modprobe the rt2x00-drivers. Seemingly the pnp-driver is blocking the rt61pci-driver from being inserted:
rt2x00pci -> rt2x00pci_probe: Error - PCI request regions failed.
rt61pci: probe of 0000:03:00.0 failed with error -16

The wireless-card:
03:00.0 Network controller: RaLink RT2600 802.11 MIMO

The memory-region-allocation:
feb00000-febfffff : PCI Bus #03
  febf7400-febf74ff : 0000:03:03.0
    febf7400-febf74ff : r8169
  febf7800-febf7fff : 0000:03:02.0
    febf7800-febf7fff : ohci1394
  febf8000-febfffff : 0000:03:00.0
    febff000-febff7ff : pnp 00:0a

I already tried pci-routeirq, which doesn't help. I was thinking of disabling pnp, but it that really what I should do???

I would think that the pnp-driver (if that is what hapenning) shouldn't be blocking other drivers.

Any idea why I am getting this message (not completely sure) and maybe how to resolve it?

Thank you and greetings,

Michel

Re: Can't use rt2x00-drivers: PCI request regions failed

I assume this is a plug-in card ?

I had a similar problem with a pcmcia UMTS card on my latop that was caused by the pcmcia cardbus driver using wrong values for memory and io ranges.

Below is what i did to solve it, maybe it helps you also :

- use lspci -vv  to determine what memory/io ranges the pcmcia bus NEEDS.

- comment out all ranges in /etc/pcmcia/config.opts

- add the ranges you get from lspci -vv

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
