I've made a hackish change to syscall stuff that works well enough but breaks o32 support; it should be obvious how to fix that: http://svn.freebsd.org/viewvc/base/user/jmallett/octeon/sys/mips/mips/trap.= c?r1=3D204399&r2=3D204534&sortby=3Ddate I'm fighting with rtld right now and believe I know the source of my misery but my tree has stopped working for some unrelated reason so now I'm trying to figure out what I messed up. BTW I've found it very useful to work with WITHOUT_DYNAMICROOT while I worked on the issues more fundamental than the rtld problem. Trivial signals seemed to work fine. Juli.
