I've tried kldloading sem (on i386) and I was pretty sure it was working.
I did that while rebuilding world+kernel after running csup.
But at reboot it's segfaulting no matter if sem is loaded or not.
So now I'm not so sure.

All my ports are updated.

I can crash it regularly loading a demo applet (e.g. ArcTest in 
/usr/local/openjdk6/demo/applets)  in a tab and then closing the tab.
If it could be of any help, I'm adding an excerpt from the backtrace I'm 
getting:

Core was generated by `firefox-bin'.
Program terminated with signal 11, Segmentation fault.
