  [Hyper-V] Ubuntu 14.04.2 LTS Generation 2 SCSI Errors on VSS Based
  Backups

Bug description:
  Customers have reported running various versions of Ubuntu 14.04.2 LTS
  on Generation 2 Hyper-V Hosts.    On a random Basis, the file system
  will be mounted Read-Only due to a "disk error" (which really isn't
  the case here).    As a result, they must reboot the Ubuntu guest to
  get the file system to mount RW again.

  The Error seen are the following:
  Apr 30 00:02:01 balticnetworkstraining kernel: [640153.968142] storvsc: Sense Key : Unit Attention [current]

  This relates to the VSS "Windows Server Backup" process that kicks off at midnight on the host and finishes an hour and half later.   
  Yes, we do have hv_vss_daemon and hv_kvp_daemon running for the correct kernel version we have.   We're currently running kernel version 3.13.0-49-generic #83 on one system and 3.16.0-34-generic #37 on the other. -- We see the same errors on both.
  As a result, we've been hesitant to drop any more ubuntu guests on our 2012R2 hyper-v system because of this.   We can stop the backup process and all is good, but we need nightly backups to image all of our VM's.   All the windows guests have no issues of course.   We also have some CentOS based guests running without issues from what we've seen.
