This is my first attempt to experiment with some form of Linux.
I created a boot USB for Elementary OS 5.1.6 Hera using Rufus. The USB stick is a 256 gb Corsair Voyager. I booted from it, saw a bunch of errors related IRQ settings stream by, and then the screen went to black and stayed there.
My PC is a recent build that functions fine with Windows 10. Ryzen 3700X, Gigabyte B550 Vision D, 64 gb RAM, older GTX 630 GPU (it was laying around), Corsair Force MP600 NVME 1 tb SSD.
So it seems the problem has "gone away"...
@KGIII Have to admit that I don't know how/where to use "noacpi"... but maybe I don't need to.
I decided to create another USB stick; used a different stick and used Etcher for Windows, but the same ISO file. Rebooted the PC, hit F12 to get the boot menu, and selected the USB stick. Still got the IRQ errors:
0.320289] do_IRQ: 1.55 No irq for vector
This repeats for 2.55, 3.55, 4.55, 5.55, 6.55, 7.55, 8.55, 9.55, and 10.55.
Then the Elementary logo appeared, pulsed a few times, and then I got the try/install screen. I selected "try" and started checking things out.
The new USB stick is a 32 gb USB 2 model. The first one was a 256 gb USB 3 model. Would that make a difference? I tried both in the same front-panel USB 3 port.
