Would it be possible for you to do a kernel bisection?
First, find the last -rc kernel works and the first -rc kernel doesn’t
work from http://kernel.ubuntu.com/~kernel-ppa/mainline/
Then,
$ sudo apt build-dep linux
$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
$ cd linux
$ git bisect start
$ git bisect good $(the working version you found)
$ git bisect bad $(the non-working version found)
$ make localmodconfig
$ make -j`nproc` deb-pkg
Install the newly built kernel, then reboot with it.
If it still have the same issue,
$ git bisect bad
Otherwise,
$ git bisect good
Repeat to "make -j`nproc` deb-pkg" until you find the offending commit.
