The system at the kernel 3.16.1 works fine (from 30 minutes), errors in the operation can not be seen, but the log looks quite impressive.
I have 47 of these messages on various modules in dmesg output.
The entire log (all messages from dmesg output):
http://jacekalex.sh.dug.net.pl/logi/infoleak.txt
During the boot before the start init appeared a long list of messages "infoleak".
Cheers
