This is also present in later distro versions, right up to Cosmic.

In my case it manifests on Supermicro and Intel 7500/5500/5520/X58 - based servers when Qlogic QLE2562 fibre optic cards are used - and _ONLY_ with Qlogic cards, nothing else seems to trigger it

As with the wifi cards on laptops, a S3 cycle stops it.
