Ertan Günay, thanks for the quick response. >"I can copy the files from anywhere to nas via MC (Midnigth Commander) in terminal with kernel 4.2.0 and the last kernel 4.3.0.rc1. Th problem happens in desktop mode with nautilus or thunar or the other same programs. I have tried to reboot system, nothing has been change about this issue. But interesting, it has a black screen instead of plymouth while booting."
Unfortunately, while you are providing more detail, you aren't providing enough organized detail to get a confirmed picture of what happens when. To clarify: 1) With Midnight Commander, there is no kernel call crash at all with any kernel version? 2) With either Nautilus or Thunar, there is a kernel call crash with Ubuntu kernel 4.2.0-7, but not with upstream 4.3-rc1? However, let the scope of this bug report be only how a kernel call trace occurs in Ubuntu kernel 4.2.0-7, but doesn't with upstream 4.3-rc1. If you are having issues with individual file managers, that would be scoped in a separate report. You may want to wait until this one is resolved first before filing additional reports. Despite this, the next step is to fully reverse commit bisect from kernel 4.2 to 4.3-rc1 in order to identify the last bad commit, followed immediately by the first good one. Once this commit has been identified, then it may be reviewed as a candidate for backporting into your release. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ? Please note, finding adjacent kernel versions is not fully commit bisecting. Thank you for your understanding.
