I have an HP Envy , model # m7-k211dx 5th Gen Intel® Core™ i7-5500U

the last couple of days where I had to avoid using the 36-generic
kernel, the only way it would boot is if I chose a previous kernel
version. Otherwise it
after regular update through `update-manager` booting on my T450s is
working again.
Thanks!

No need to test further mainlines, the backports that work fine on trusty

or, to boot with -36 in
yes it is, will be fixed once the utopic kernel is available
