Since linux 3.17-rc1 dmesg gives me one message during boot, i don't know if it is danger:

The system seems to work fine, i can't see any problems on running the system.
I thought, the dvb-module is the problem, but the dvb card works fine.
The trace i can reproduce by rmmod dvb_ttpci && modprobe dvb-ttpci.
