Does anybody know what causes the fault? Is there anyway to disable the error? Or we should install a malta bus_error_handler() to discard this kind of error? Apparently the error has something to do with the code layout as it only happens when I start to modify an unrelated function( do_ri()). I am using the latest linux_2_4 branch from oss.sgi.com CVS tree.
