 Reproduced it on another machine with working DDB:
 
 Starting syslogd.

 which is line 1060:
 
 1058            prev_active = module_active;
 1059            module_active = mod;
 1060            error = (*mi->mi_modcmd)(MODULE_CMD_INIT, filedict ? filedict 
: props);
 1061            module_active = prev_active;
 
 and obviously mi->mi_modcmd does not point to a mapped page.
