Comment 200 for bug 1470250

@alexng-v I only had this while doing backups. Also, in the initial post on MS Technet refers to it as a backup problem: https://social.technet.microsoft.com/Forums/windowsserver/en-US/8807f61c-565e-45bc-abc4-af09abf59de2/ubuntu-14042-lts-generation-2-scsi-errors-on-vss-based-backups. We are now running HyperV with linux VMs for over a year (in production) and we only see it during backups.
