I have a debug kernel and can provide some more detail : agp0: mem 0xf8000000-0xfbffffff at device 0.0 on pci0 agp0: allocatnig GATT for aperture size 0M panic: contigmalloc1: size must not be 0 Debugger("panic") Stopped at Debugger+0x54: xchgl %ebx,in_Debugger.0 I'm just getting started with this whole debugging thing so I can provide any information that you think would be helpful. If I 'continue' from the db I get: Uptime: 1s panic: Assertion mtx_unowned(m) failed at /usr/src/sys/kern/kern_mutex.c:963 if that helps.
