Status in linux package in Ubuntu:

Bug description:
  Description:
  On Ubuntu 16.04 running 4.13.0-32 kernel, when file IO stress is run on 
multiple NVMe disks (ext4 partitioned), system hangs with multiple kernel 
crashes in the logs.

  Steps:
  1. Setup a DellEMC AMD servers with a few NVMe disks.
  2. Run the file IO stress on these disks for 24 hours.
  3. Observe that the system goes un-reponsive after a few mins/hrs.

  Additional Info:
  * Stress ran fine for 24hrs with 4.12.0-041200-generic.

  * Stress ran fine for 13hrs with 4.10.0-28-generic. Had to stop the
  run manually due to some other reasons.

  * Stress fails with linux-image-4.13.0-25-generic.

  Attaching the logs.
  Will update here once we have more data.
