Please use linux_kdump or truss, the FreeBSD kdump doesn't translate  
Linux syscalls.

That's the default.

Do you have the right ld.so.conf (LINUXBASE/etc/) and  
ld.so.conf.d/xorg-x11-i386.conf? The linux ldconfig has to be run  
(chrooted). To be on the safe side remove all linux ports, clean  
/compat/linux, and resinstall the linux ports. Currently it sounds  
like a ldconfig problem...

Bye,
Alexander.
