Comment 3 for bug 594866

I forget to say that it worked fine before (<= 2.6.31).

And also I don't know if it's related but now if I shutdown (not reboot) the computer and restart it later, it seems that this wireless card is disabled and I can't enable it with:
  $ sudo ifconfig wlan0 up
The output says that the device is busy. This is what I've from 'dmesg'
   [ 43.762591] phy0 -> rt2800pci_load_firmware: Error - PBF system register not ready.
   [ 43.763112] phy0 -> rt2x00pci_regbusy_read: Error - Indirect register access failed: offset=0x00007010, value=0xbdfcfb7b

I can't enable it at startup because the related option on the BIOS setup has only two possibilities: "Disabled" and the "same status just before the shutdown".
