nixpkgs/pkgs/os-specific/linux/kernel/cifs-timeout.patch
Eelco Dolstra cb5bcfa04a * In the VM tests, apply a patch to increase the 15s timeout on CIFS
operations to 120s.  This is necessary if the host is heavily
  loaded.  For instance, in the Hydra build farm, if there are many
  concurrent jobs, VM builds often fail because they hit the timeout.
