Hi Joseph I upgraded kernel to "4.3.0-040300rc1-generic". And then system does not lock up anymore. But the files that I'd like to copy from sdc1 to NAS, still couldn't copy. After problem apport give following error:
It appears you are currently running a mainline kernel. It would be better to report this bug upstream at http://bugzilla.kernel.org/ so that the upstream kernel developers are aware of the issue. If you'd still like to file a bug against the Ubuntu kernel, please boot with an official Ubuntu kernel and re-file. I'll try to reboot system again.
