Ubuntu - Firmware - Update latest AMDGPU firmware

Backed up the existing 14 'navi10_*' files to /lib/firmware/amdgpu/.

NOTE: Other files could also be possibly used is the latest Kernel ones do not work. For instance:

Copy all 14 'navi10_*' files from the downloaded firmware file to /lib/firmware/amdgpu/.

Update the initramfs

Ensure that compress=lz4 is set in /etc/initramfs-tools/initramfs.conf.

NOTE: compress=gzip used to be used, but newer Kernels use lz4.

sudo update-initramfs -c -k $(uname -r)

sudo update-initramfs -k $(uname -r) -u

NOTE: The above does only the current Kernel. For all Kernels use:

sudo update-initramfs -k all -u

Reboot
