How to reproduce: Copy some large files from local filesystem to CIFS mounted filesystem.

How often does it occur: Every time, after a few minutes or so. Affected kernels: Bionic 4.15.0-23-generic and forward. I also tried 4.15.18-041518-generic and 4.16.13-041613-generic from ubuntu archives an got similar GPF. 4.13.0-43-generic from ubuntu 17.10 not affected.
