5.9: Screen turns on only after rootfs is mounted and modules loaded
Seems like some things needed for the screen to work have been moved into modules with 5.9, which makes it stay dark until rootfs is mounted and modules are loaded from there. This is annoying especially when the boot doesn't continue for some reason and the screen just stays dark forever (which happened to me a few times already).
Alternatively it should be made sure that all the required modules are included in initramfs in PureOS.
