Ubuntu freezes at the login screen or, if one is quick enough, shortly after typing a few chars of the password.
Sometimes nothing except the power button works, at times I could reboot via endless massaging of sysrq + b.
Last good kernel: 4.15.0-13
Mainline 4.16.3 is also affected.
Mainline 4.17rc1 is good again.
