<p>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).</p>
<p>Quick check on the net, it may have to do with module.sig_enforce
option for kernel loading.</p>
<p>Cheers,<br>

<div>So it turns out my rtpengine stopped working

<div>As soon as we started making test calls, I
received 0 audio from those test endpoints.
Looking at the rtpengine logs, I see several
