Hi, we experience a Kernel Oops with the latest PF_RING (SVN revision 4150) when the kernel module is loaded. I attache the messages related to the oops.
We use a vanilla 2.6.32.4 kernel which no PF_RING capable driver loaded. Can we send any further information that could help to debug the problem?
