Did so, attached is the dmesg output after 3x suspend.

It also seems this bug gets more / only triggered when I loose the
connection to a wpa2-eap network that is defined like this:

network={
   ssid="eth"
  id_str="eth-802.2x"
   key_mgmt=WPA-EAP
   proto=WPA2
   eap=TTLS
   pairwise=CCMP TKIP
   group=CCMP TKIP
   phase2="auth=MSCHAPV2"
   identity="MYNAME"
   password="forgottoremoveit"
}

Hope the dmesg output helps and we can remove the problem soon
and making the mba finally almost completly usable :-)

Cheers,

Nico
