Hi!I have some Debian 8 system with CIFS shares mounted with the option vers=3.0.
Since the last kernel upgrade (linux-image-3.16.0-6-amd64 to the version 3.16.57-2) and the new kernel installation (linux-image-3.16.0-7-amd64 (version 3.16.59-1) both kernels are crashing while mounting the CIFS share:
