Pau, It seems that your patch made my atheros card fail to find the AP.
I upgraded wpasupplicant from 1.0-2ubuntu1 to 1.0-2ubuntu2 today.
after reboot, my card cannot connect to the AP.
I run
sudo /sbin/wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -dd
to see what happend, and I got these:
...
Scan SSID - hexdump_ascii(len=7):
XX XX XX XX XX XX XX *******
wlan0: Starting AP scan for specific SSID(s)
Scan requested (ret=0) - scan timeout 10 seconds
EAPOL: disable timer tick
EAPOL: Supplicant port status: Unauthorized
RTM_NEWLINK: operstate=0 ifi_flags=0x1003 ([UP])
RTM_NEWLINK, IFLA_IFNAME: Interface 'wlan0' added
WEXT: if_removed already cleared - ignore event
Wireless event: cmd=0x8b19 len=16
wlan0: Event SCAN_RESULTS (3) received
Scan results did not fit - trying larger buffer (8192 bytes)
ioctl[SIOCGIWSCAN]: Argument list too long
wlan0: Failed to get scan results
wlan0: Failed to get scan results - try scanning again
...
after downgrade to 1.0-2ubuntu1, using the same command, I got these:
...
Scan SSID - hexdump_ascii(len=7):
XX XX XX XX XX XX XX *******
wlan0: Starting AP scan for specific SSID(s)

Received 7564 bytes of scan results (14 BSSes)
wlan0: BSS: Start scan result update 1
...
I checked the changelog of wpasupplicant, It showed that the only
difference between 1.0-2ubuntu1 and 1.0-2ubuntu2 is
fix_driver_wext_for_broadcom_wl.patch
