What kernel module(s) is your dkms supposed to build? This may depend
on what they are for but try renaming the initrd file by removing the
.dup_orig and see if that allows the system to boot.
An attempt to rebuild initrd will probably reveal what went wrong.
/sbin/weak-modules created those .dup_orig files. I suspect the
problem is related to the module(s) built by dkms.
