Hi Brad,
We have tested the -proposed kernel and it resolves the issue for us. I
have updated the "verification-needed-xenial" tag to "verification-done-
xenial".
Thanks again for the prompt response on this.
** Tags removed: verification-needed-xenial
** Tags added: verification-done-xenial
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
xenial' to 'verification-done-xenial'. If the problem still exists,
change the tag

Hi Joseph,
We gave it a try internally and it looks good. Passed the same set of
tests I ran with the previous kernel you provided: works with mq
disabled, enabled and also passes a simple io integrity test.
Thanks,

Hi Joseph,
Thanks for looking at this so promptly. I have downloaded and tested
your kernel. It appears to work well both with scsi mq enabled and
disabled (over virtio-scsi). I also ran some basic io integrity tests
and didn't spot any problems.
Before you commit this, may I propose a v2 of my
