I'm very suspicious to the claim of failing hw since trace is the same all
times (is this true) ? This looks like memory corruption.

First, I would recommend to update to RELENG_6 due to a number of VFS fixes.
Second, could you set kern.maxvnodes in the /boot/loader.conf ? Check the
value choosen by kernel by "sysctl  kern.maxvnodes", and then set it
to the 2/3 of the reported number and reboot.

If I not gather any useful info from that action, I most likely provide you
with debugging patch.
