Since this morning, the machine is running with the dvb driver for that certain card unloaded... Anyway you convinced me that it is the bad saa7134_dvb drivers (driving the asus p7131) fault. As the driver seems huge, I wonder whether there are a) other config debug options that could aid in debugging b) what the names of certain io functions are that may cause this... Thanks a lot!
