Since a recent merge of the wireless tree to Linus' master, my SDIO
connected libertas module fails to connect to our WLAN.

'iwlist scanning' works fine, but wpa_supplicant keeps on spitting out
the following message:

  CTRL-EVENT-SCAN-RESULTS
  Trying to associate with 00:04:0e:4b:c7:b3 (SSID='caiaq' freq=2437 MHz)
  Association request to the driver failed

Haven't done any bisect or deeper inspection of recent changes yet. Can
anyone point me in some direction maybe? The change must have been
introduced between -rc3 and -rc5. My userspace did not change since
then.

Normally a bisect is exactly what you would do.  In this case, there
is only this on libertas patch in the range you mention:

    libertas: Fix problem with broken V4 firmware on CF8381

    Firmware V4 on CF8381 reports region code shifted by 1 byte to left.
    The following patch checks for this and handles it properly.

If you revert that, does your problem disappear?

Hi!

Those SDIO cards should use FWv9 or something so this patch should have no 
effect.
