I built a kernel from this morning's sup and it dies on a "Dell Dimension 486DX250" with the panic: > pmap_zero_page: CMAP busy It starts up single user fine, but will panic as soon as you type ps. "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.
