Problem with WIFI in 10.10

Since I've upgraded to 10.10 on my eepc 901 I have problems reconnecting to WIFI after suspending the computer. Looking the system log I get this message:

The only way to connect again is to reboot :-(

Thanks for your help or for passing it on to whoever would be able to fix this bug ...
