Comment # 3 on bug 1175994 from Michael V

After following [Debugging boot
hang](https://en.opensuse.org/SDB:Debugging_boot_hang) and replacing `quiet
splash=quiet` with `debug initcall_debug`, the system gets all the way to

```
fb0: switching to inteldrmfb from EFI VGA
```

and just hangs there. No keyboard input accepted. Only hard reboot with power
button works. Note again that this happens **only** with kernels above
5.6.14-1.

Somewhere else I found that nomodeset might help and it does to some degree. It
boots, but the second screen doesn't work and I can't change the resolution of
the main laptop screen.

There was a regression somewhere and I have no idea how to bisect a kernel. I
have a debug kernel also installed, but I don't have the foggiest on how to use
that yet.
