I just built a kernel statically & found it. Apparently, the vm_mtx must be held around vm_map_find(), vm_map_findspace(), and vm_map_lookup_entry(), and probably others. Is there any documentation what the locking requirements of various vm functions are now? I tested osf1 after my initial set of commits to catch alpha up to x86, but an assert must have been added since then. Anyway, grab 1.16 of osf1_misc.c and 1.6 of imgact_osf1.c I can now run netscape with a top-of-the tree kernel.
