I use an ASUStek WL-167g USB wlan adapter (quite old) using rt73usb.ko
(Ralink). After resuming from suspend I get:

[152743.736783] ------------[ cut here ]------------
[152743.736798] WARNING: at net/mac80211/driver-ops.h:12

[152743.736804] wlan0:  Failed check-sdata-in-driver check, flags: 0x4

Does it still happen on 3.5.1 ?

Thanks for asking. With 3.5.1 I get "phy0 -> rt2x00lib_request_firmware:
Error - Failed to request Firmware."
But:
$ wc /lib/firmware/rt73.bin
  5 44 2048 /lib/firmware/rt73.bin
So I wonder were that comes from. udevd segfaults twice while hotplugging
the device. And finally I get "link becomes ready" but I get ENODEV when
starting wpa_supplicant. It all seems a bit weird and I have no idea how to
debug this.

I will try putting the firmware blob into the kernel binary.

Looks like some change broke udev, but how? Do you have the same thing with
3.5.0 ? Perhaps updating udev could help.

You do not use NetworkManager or similar only pure wpa_supplicant? That would
explain why I'm not seeing the problem on my setup. Could you provide me 
your wpa_supplicant.conf (after removing psk and ssid entries) ? 
What wpa_supplicant version you are using?

Thanks
