Pyun recently MFCd to stable (hence my post to this list) some changes to bge that involve functions in the above trace and according to the commit log (r201685) may address a kernel panic. Is there any indication in the above trace that this is the type of panic the commit attempts to address? I don't have a core dump for this panic. This machine has been unstable on 8, so I may be able to get a core dump in the future. If there is other information you'd like me to gather, please let me know. Thanks, Erik
