Hangs are hard :-) It just sits there with a black screen and a white
cursor in the top left corner...

Yes, I am using NM under KDE, with KDE triggered suspend. No wowlan
AFAIK. The last thing I see in the log is something from NetworkManager
that sees the device switching off. I can try again tonight and give you
the exact message.

I will also try without NM and bare wpa_supplicant and a plain suspend
through sysfs.

Any debug options you want me to enable? Netconsole won't work however...
