Description

I'm using a Multilink L2TP WAN. After a fresh reinstall of 2.4.4 and completely new config (no import) it crashes regularly. The crashdump always has the same stacktrace showing a page fault while copying a packet for retransmitting after a timeout.

Fatal trap 12: page fault while in kernel mode
