Comment 37 for bug 1827884

I have a Lenovo G500 (32 bit laptop about 5 years old).

I am seeing the same behavior on my system. Booting 4.15.0-47-generic works fine, but both
4.15.0-48-generic and 4.15.0-50-generic usually hang at boot time. If I enter grub at boot and select 4.15.0-50-generic, it usually hangs at this:

Loading Linux 4.15.0-50-generic ...
Loading initial ramdisk ...

If I let the system just boot up w/o going into grub I don't see the above. I usually either get a solid blank purple screen or a blank purple screen with a bar of random colored pixels across the middle of the screen.

Now yesterday I was able to get 4.15.0-50-generic to boot all they way into the GUI after booting it from the grub menu and was able to use the system for the rest of the day, no problems. So it seems to be a startup only problem.

When in the hung state, I can't get to the console screen via the usual Fn-Ctrl-Alt-F3.
