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.
