"ps" will go in to "pmap_zero_page" 26 times and on the 27'th time will find that CMAP2 is already non-zero. The Stack backtrace is pmap_zero_page vm_page_zero_fill vm_fault trap_pfault trap(27, ...) I don't have much experience with this system though it boots the GENERIC kernel on the last SNAP fine. -- Peter Dufault Real Time Machine Control and Simulation HD Associates, Inc.
