In the course of trying to get that setup working we seem to be running into behavior from Xorp that is causing kernel panics to happen on FreeBSD 8.3-RELEASE. Currently, we are able to startup Xorp normally with no apparent problems. However, as soon as we try to shutdown the Xorp service or initiate a system reboot the system will kernel panic. We are running Xorp on ALIX1.D single board computers. You can see more about the hardware specs here: http://pcengines.ch/alix1d.htm I have created a file dump of some of the kernel panics along with some kdbg backtraces for developers to take a look at (along with a kernel.debug for our kernel build). If I am reading the backtraces right, it looks like there might be an issue being caused by IGMP somehow. Perhaps a mismatch between v2 and v3? http://www.mediafire.com/?ojxdc172mp7q6 >How-To-Repeat: Install Xorp 1.8.6 from Git repo source Run Xorp doing IGMP and PIM-SM Attempt to stop Xorp service or Attempt to reboot server Kernel Panic occurs >Fix: None that I am aware of. >Release-Note: >Audit-Trail: >Unformatted:
