Linux kernel 5.2-rc4 messages

There is a regression between Linux 5.2-rc3 and 5.2-rc4.

The screen just freezes with start-up messages (mainly systemd notifications),
and the login screen is not shown. Logging in remotely using SSH is possible.
The X server cannot start as no screens are found. Linux logs the messages
below.
