[cardigliano]

Something went wrong recompiling the dkms modules. Please 1. remove the packages, 2. reboot the machine to the latest kernel, 3. reinstall the drivers

[a-czyrny]

Deleting, restarting and then reinstalling has helped. How do I ensure that a kernel update does not ‘break’ pf_ring?

[cardigliano]

dkms should automatically recompile the kernel modules when updating the kernel, however if the kernel update is installed, but the kernel is not activated with a reboot, under some circumstances the makefile picks the wrong symbol creating this issue. We will dig more to check when this happens and try to avoid that.
