To answer my own issue, and document it for others in the future, the problem was due to some kernel module objects in /lib/modules/<kernel>/weak-modules and /lib/modules/<kernel>/extras that hadn't been properly removed at some point. Removing all associated pf_ring RPMs, removing these files, and reinstalling the RPMs resolved the issue.

Subject: [Ntop-misc] Kernel panics after upgrading to pf_ring 6.4.1


Hello all,


I'm attempting to upgrade pf_ring via the stable rpm packages to 6.4.1. The RPMs install (with errors noted in the pfring package installation) as shown below. However, when I attempt to start the pf_ring service the box kernel panics and gets into a reboot loop. I've attempted removing pf_ring entirely and reinstalling but so far that has not helped. This is a RHEL 7 box. Any ideas?
