[SOLVED] Fail to resume after suspend using lid and other issues

[majuamst]

I am a brand new user of Linux on a 10 year old laptop with a C-60 AMD GPU. Immediately upon booting, there is a brief message, "0.004051 Common interrupt 1.55 No IRQ handler for vector" that flashes for 10-15 seconds. The computer continues to boot into LinuxLite. I am a longtime Windows user and a brand new Linux user. I am learning to like LinuxLite and have set up this old laptop to do everything the way I want, but I have one very big problem. It will not wake up from suspend. It flashes "no IRQ handler for vector" on several lines of a black screen. The error message disappears too quickly for me to copy and post it accurately for you to see. After the error message, the screen stays blank and never loads my desktop. I have tried to use hibernate instead, but I get another error message indicating that hibernate is not possible. It appears that some IRQs are not being assigned upon boot and after suspend.

I did some internet research and found that this is a known issue with AMD processors. It has something to do with IOMMU. The suggestions include turning IOMMU off in the BIOS, but that option is not provided in the rudimentary BIOS screens of this ACER Aspire One 722. Apparently there is a Linux software solution as well, but they all suggest the BIOS change first.

Sorry for the long post, but I am wondering if someone has experienced this issue and knows how to fix it. I really want to learn Linux on this old laptop and have started tutorials to navigate my way around. As we get closer to Microsoft abandoning Windows 10, I would like to convert all of my networked computers to Linux, but not if I cannot solve these types of problems.

Thank you for being here for beginners like me.
