I was intermittently experiencing the same problem, also using SMP 
x86_64.  IIRC Ardour's built-in denormal protection didn't help for some 
reason.  At one point I tried modifying the TAP source and posted a 
patch here:

I've not had any confirmation from anyone on whether or not it helped. 
In fact, I can't remember if it worked 100% for myself or not.  I'm 
afraid it's been quite some time since I did any audio work at all.  But 
you might want to try it if you're out of ideas.

Also there was an attempt at writing a denormal-safe SSE2-optimised 
alternative to TAP EQ by Mike Taht, as mentioned here:

The download link (which appears to be broken in the list archives) 
should be:

Again, I don't really remember if those plugins worked fully or not.  I 
must have really terrible memory as it was only about six months ago.
