Related to tainted kernel, I faced the same issue when I deployed rtpengine on a Suse Enterprise many months ago, so I do not really remember the exact steps, but there is a way to disable the check of signed kernel modules (iirc, these are only the ones coming from the kernel source tree, so if you need to load any external kernel module, you have to disable this option).
Quick check on the net, it may have to do with module.sig_enforce option for kernel loading.
