Your Linux kernel is very old, version 2.6.29 was released over 8 years ago. Please try a recent kernel such as 4.8.0 instead so that you don't miss all the important fixes and updates. If you find yourself still having issues with an updated kernel, then please come back and we'll try to help. Maciej
