Verified on 16.04 with the daily ISO (2017/07/11).
Just noticed a glitch with grub-installer and multipath,
but that's not related to this bug. I'll report a new one.

Verification done for yakkety's multipath-tools SRU:
multipath-tools 0.5.0+git1.656f8865-5ubuntu7.3
I verified that multipath-tools correctly ships its new hook to include
dm-service-time and dm-queue-length, and the system with that update
boots successfully.

The hw-detect change is uploaded, so once it's in the archive, installs
on hardware requiring dm-queue-length should work without issues.
We're still blocked on having the kernel include dm-queue-length and dm-

Please assign this bug to @cyphermox for the multipath-tools components, at

He's handled most of the multipath-tools related bugs/patches we've been
