Computer: Lenovo Ideapad S145, amd ryzen 5 3500u. SSD 120gb(SO) + hd1t
I recently installed Linux Mint on my computer. And these errors have appeared when starting. When these errors appear and turn on, and at other times these errors appear and go to a black screen.
Please, does anyone know why?
I'm running debian on my laptop Lenovo XiaoXin pro13 (Ideapad s540 13) AMD ryzen 4800u, and encounter the same issues.
I fixed the " AMD-Vi: Unable to read/write to IOMMU perf counter" by editing the grub config file at /etc/default/grub and added
GRUB_CMDLINE_LINUX="iommu=soft"
and update grub config by execute
sudo update-grub
To fix another error just go into your laptop bios, disable the Secure Boot and Reset it to Setup Mode
