I've made a new test without using your testing rootfs-uImage for now (I
had few minutes to perform it :P) but using the latest Andy's image:
 uImage-moredrivers-GTA02_stable-tracking_e7d89a2acb5da003-GTA02.bin

The first time I've loaded my FR with it, I logged in SSH just while the
phone was booting (Illume wasn't there yet) and I was able to run
ifconfig/iwconfig quickly (but I didn't test the iwlist scan). I waited
Illume to be booted and the above commands were still running fine; then
I've made the mistake of letting my phone suspend and just after
resuming I got the "hanging bug": ifconfig/iwconfig were slow to show
informations about eth0 and "iwlist eth0 scan" - after hanging for some
seconds - didn't show any result.

So, I booted again but disabling the auto-suspend this time. After my
phone loaded I ran again the same commands but this time I was able to
i[fw]config quickly, scanning and connecting using wpa_supplicant.

Finally I got associated with my AP. I wasn't able to get an IP from
DHCP but this always happened with this router (who knows why?! I've two
routers practically identical running both dd-wrt and in this one I
can't get an IP from DHCP); however manually setting my IP and the
routing I was able to connect.

Then I've suspended my device and... The hanging bug was back!
However this time, running "iwlist eth0 scan" I was able to see only the
network I was associated before hibernating (and that according to
iwconfig I was still associated to)... Also re-running wpa_supplicant
was practically impossible (it was hanging too).

So the problem seems to stay on the suspend/resume actions that
completely block my wlan.
