It could be a memory problem. Could you also please apply an assert to pmap_enter_quick() + INVARIANTS. This is a quick test that checks all the other paths that call pmap_enter_quick() are locked out so that two processors cannot be using the PADDR1/PMAP1 at the same time. --- pmap.c.orig Mon Aug 25 08:46:03 2003 +++ pmap.c Tue Aug 26 07:16:06 2003 @@ -2056,6 +2056,7 @@ pmap_enter_quick(pmap_t pmap, vm_offset_ pt_entry_t *pte; vm_paddr_t pa; + mtx_assert(&vm_page_queue_mtx, MA_OWNED); /* * In the case that a page table page is not * resident, we are creating it here. --Mark Tinguely tinguely@casselton.net
