@proton,
Sorry for the late reply, I was out of the office for a couple of weeks.
Thanks for your feedbacks, I'll submit the patch to be backported into
4.4 kernel.
Note that we will need your help for testing one more time if the patch
is accepted into the -proposed archive.
I'll keep you post
@slashd
Sorry for the delay.
The kernel you provided works as expected, while on the same machine
4.4.0-31 fails.

The test kernel I made is for the Xenial release, not for Trusty.
Do you experience the problem on Trusty ? Originally the problem was

@Proton, Thanks for the feedback for v4.6-rc1.
Dale, Proton,
I built a test kernel [4.4.0-30.49hf1572630v20160706b2] based on Ubuntu Xenial
kernel v4.4.0-30.
It is including the fix introduced upstream in v4.6-rc1 that can be found on my
PPA :
$ sudo add-apt-repository ppa:slashd/buglp1572630
@slashd
v4.6-rc1 works as expected.

To continue my comment #11 ...
There is more commit to apply, since commit 897bb0c remove ‘int i;’[1]
in function ‘blk_mq_sysfs_init’, it won't build in function
‘blk_mq_sysfs_init’, ‘queue_for_each_hw_ctx’ still load ‘i’ as an
argument, but it is no longer declared after commit 897bb0c[1].

Hi Dale, Proton,
Can you confirm if you can reproduce the problem or not using the
mainline kernel v4.6-rc1 found in :

At first glance, theses 2 commits are needed to fix the issue, 897bb0c7
is the fix but won't build if e0e827b9, since it removes the function
"queue_for_each_ctx" that will no longer be defined in the header file
after "897bb0c7".

There is an upstream fix for this issue.
