I have a very similar hang when copying files. After a few files copied, it hangs. Forever. I have a kernel warning stack trace:

Reproduce; it helps if you play a video/movie using vlc or mplayer from share. the file should be open for hours. (use pause) - when unpaused, the file will play fine. -no new big files on that share will open, small files may work. unmounting + remounting the SMB share may fixe the problem, but other processes may be affected: VLC - while stuck with such samba problem, is impossible to kill, same for smplayer sudo killall vlc -s KILL .. will not kill it. and so unmounting the share takes >10 attempts..
