 I have been able to reliably reproduce this with: 
 while (1)
  mplayer -ao null -vo null somefile.avi
 and the box would keel over in a few minutes.  However: after updating 
 my -current kernel to have this fix:
   cvs rdiff -r1.142 -r1.143 src/sys/uvm/uvm_page.c
 I have been unable to reproduce the panic!!!  (it's been 2 hours of 
 pounding now, where before it only needed about 5 minutes...)
