Comment 15 for bug 1687273

This problem hit me on a xenial install with HWE and linux-generic-hwe-16.04 with generic kernels 4.8.0-52 and 4.8.0-53. Problem is alleviated by using the mainline kernel 4.12-rc2.

Please note: I cannot use the vers=3.0 workaround as described above because one of my servers is running Windows Server 2003 which, as I understand, still uses the older SMB1 protocol.

This problem happened on a users workstation and due to the freezing problem with the desktop and file manager, her system was unusable for about 2-3 days.

It took me a little while to pin-point the problem to a complete cifs freeze which was occurring within 5-45 minutes of logging on.
