I have the same issue (same stack trace in dmesg). When the share becomes inaccessible (my home router crashes often) most apps hang indefinitely (including plasma desktop). There remains a lock active and I cant't even unmount the share until I kill the app that initially accessed the (unavailable) cifs share.
