journalctl output
I'm getting a black screen on boot when testing the 5.4 release candidate
kernels on a Dell Inspiron 7375 laptop. The system responds to the magic sysrq,
so the kernel is not completely dead, but the display is. The system boots
correctly with a 5.3.1 kernel. The log showing the stack trace is attached.
I'll start working on bisecting the problem soon.
