The System unloads the ec_e100 driver without a problem. The Freeze appears
when i am loading the e100 driver again. But in the Syslog file there is no entry about inserting the e100 module.

The last entries of my Syslog are:

I hope this helps tracking down the problem. Tell me if you need further information.
