[Bug 1794318] [NEW] kernel update breaks boot on intel fake raid 1

[Jeroen]

Public bug reported:

My system won't boot after a kernel upgrade. When I switch back to the previous kernel version it works fine.
I've got 3 ssd's and 1 hdd.
Currently I'm using 2 ssd's for intel fake raid 1(mirror) for kubuntu 18.04
The last ssd has windows 10 installed.

My hdd is currently unused.

I've reinstalled my system multiple times. I can reproduce this kernel
boot problem every time.

Fake raid 0 has worked on my system for a a few years now. 
My fakeraid 0 setup broke somewhere on the beginning of september.  
Possibly with the same root cause.
