--- Comment #14 from Gordon Bergling <g...@freebsd.org> --- (In reply to Michael Tuexen from comment #13) Thats correct. If the Stack is loaded via /boot/loader.conf the system panics, when the first real network traffic, in my case an attempt to mount a NFS share, is happening. When booting with default network stack the system panics, when loading the tcp_rack or tcp_bbr kernel module. The panic including the backtrace are the same. -- You are receiving this mail because: You are the assignee for the bug.
