Problem Description

The suggested install procedure of amdgpu-dkms on https://rocm.docs.amd.com/projects/install-on-linux/en/latest/install/quick-start.html for Debian 13 via the Ubuntu deb archive file https://repo.radeon.com/amdgpu-install/7.1/ubuntu/noble/amdgpu-install_7.1.70100-1_all.deb produces a amdgpu module set, that is too large for most standard /boot partition sizes in Debian 13. Thus the amdgpu-dkms undoes the install, but still calls the update for the initramdisk, which is too big for the /boot partition and fails. Thus the apt process breaks and also the amdgpu drivers are not available properly. For the ROCm/PyTorch libraries a custom OEM kernel at least 6.14 is required and i installed the Debian 13 Trixie backport kernel 6.16.12 together with the previous kernel, so only two kernels in /boot and too less space for the initramdisk. The size of my Debian 13 Trixie standard install /boot partition is about 455 MB, which is not so small. Then the apt process is broken
