There's a good chance this problem has been fixed already. You are using a v4.4 kernel with many patches applied by Ubuntu. Here, we are more concerned with the latest kernels, and v4.4 is quite old. Please test some of the later kernels, see https://wiki.ubuntu.com/Kernel/MainlineBuilds In particular, test v4.13 or v4.14-rc4. If the problem still happens, capture the same information and send it again as a reply. If the problem doesn't happen, then you can either continue to use the new kernel, or find when the problem was fixed; a long but rewarding process. Should the problem have been fixed for v4.10, you might also switch to using the Ubuntu package linux-generic-hwe-16.04. https://wiki.ubuntu.com/Kernel/RollingLTSEnablementStack#hwe-16.04 Hope that helps. > Thanks. > > Regards > > Mario [...] -- James Cameron http://quozl.netrek.org/
