commit 5db9ff87ac04da152ac8996025158f010adbfa8f Author: K. Y. Srinivasan <k...@microsoft.com> Date: Fri Jun 5 14:00:31 2015 -0400 storvsc: Set the SRB flags correctly when no data transfer is needed BugLink: http://bugs.launchpad.net/bugs/1439780 Set the SRB flags correctly when there is no data transfer. Without this change some IHV drivers will fail valid commands such as TEST_UNIT_READY. This commit was included per bug 1439780 and is confirmed to have resolved that bug. The 3.19.0-22 kernel is now in the proposed repository. Would it be possible for you to test this latest kernel and post back if it resolves this bug? See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

It is needed for 15.10, 15.02, 14.10, 14.04 and 14.04 HWE (and, by extension, 12.04 and 12.04 HWE). We have seen IHV drivers in the field throw errors and time out due to receiving SRB flags set when no data transfer is expected. storvsc: Set the SRB flags correctly when no data transfer is needed Set the SRB flags correctly when there is no data transfer. Without this change some IHV drivers will fail valid commands such as TEST_UNIT_READY.
