I tried putting `bootdev' (0xa0500004 = some slice on sd0a) in npx0's id_maddr. This failed because kvtop() is called on id_maddr just to print its physical address (after id_maddr has been converted from a physical address to a virtual address). The bug seems to be that kvtop() only works for valid addresses and id_maddr is invalid if it wasn't originally between 0xa0000 and 0xfffff. Config and userconfig don't restrict the address. Bruce
