Title:
  APM Mustang board kernel crashes when running Ceph

Status in “linux” package in Ubuntu:
  New

Bug description:
  Hi,
  We've been running Ceph on 4 APM Mustang boards within Linaro, running stock Ubuntu Utopic (problem occurs with Trusty too).

  Essentially when I place the network under heavy load (by writing data
  to a Ceph filesystem backed by 3xOSDs), I experience kernel crashes.
  I've harvested a few backtraces from the serial port and will paste
  them below as separate comments.

  I think the problem lies in the xgene driver, but I don't know enough
  to resolve where this problem is happening.

  Cheers,
  --
  Steve
