You are the third person to report this panic. (I am one of the other two. I am guessing from the name of your kernel that this is an SMP system. So are the other two. Are you running gnome-2.16 with hald? This is about all we found in common on the first two systems. Robert Watson would like some added data. Can you build a kernel with the following options and connect something to the serial port to record output? options WITNESS options INVARIANT_SUPPORT options DDB options KDB options INVARIANTS At the debugger prompt: > show pcpu > trace > show allpcpu > traceall > show alllocks At least my system has been totally uncooperative in crashing when I am anywhere near it, so I have not yet collected any information other than dumps. -- R.
