Hi,
today I have go the following warning several times but it's not
reproducible systematically. It happens at boot when the USB wireless card is
already connected and the wpa_supplicant is restarted to connect to the AP.
The kernel version is v2.6.33-rc2-47131-gc72a18c.
This are the kernel messages I get soon after boot

Then here I restart the service responsible for wpa_supplicant and I get
