Hello,

Looks like Debian Live Distro needs the following option for kernel in GRUB config file if GPU driver is installed..

nomodeset amd_iommu=off iommu=pt

Else it will hang with series of DRM bit flip timeout error messages... Has anyone experienced this before?

with "nomodeset amd_iommu=off iommu=pt" I was able to circumvent the problem..But there should be a better way without disabling the GPU driver..

I am using Ryzen 3 machine...

Regards

Rajaneesh
