I blacklisted the nouveau module, made a new ramfs, installed grub and so on. But the boot process hangs at the point where the radeon module is loaded. With „nomodeset“ and having the NVidia card connected it gives the error message about missing UMS/KMS at the point (and boots). So I’d expect driver loading/mode setting to happen there, but it does not. Any helpful idea out there? Thanks Johannes
