I'm not sure that there is a "clean" way to do this since higher level bounce buffers really have no business being used when the system is writing out a crash dump. I think in this case the driver dump routine should be modified to work around the 16MB limitation (yuck). -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
