Created attachment 66342 [details] full trap log, dmesg, iptables, lsmod, ipset Hi! I set up the server with the new software. It must serves users with VPN connections (l2tp,pptp - kernel mode). As soon as I start the users it hangs. With latest drivers from Intel (igb) and the latest kernel (2.6.39.3) it hangs (rarely) or a kernel panic (most often) in 1-2 minutes, when users log on to the NAS server and starts to go traffic on VPN connections. I tried to turn off the incoming shaper on the ifb, disable, conntrack(-j NOTRACK in the RAW table), was trying to use only PPTP - the kernel still hangs or falls into a panic.
