Comment 19 for bug 1763189

I tested the following mainline packages:

linux-headers-4.16.0-041600_4.16.0-041600.201804012230_all.deb
linux-headers-4.16.0-041600-generic_4.16.0-041600.201804012230_amd64.deb
linux-image-4.16.0-041600-generic_4.16.0-041600.201804012230_amd64.deb

Still unbootable except in recovery mode.

The only difference, 4.16 generates new messages about missing firmware that neither 4.13 nor 4.15 generated:

I tried installing nouveau-firmware with no difference.
