I had strange issues with DAHDI and HT enabled. This was with Debian 6 
about a year ago with a Digium 4 and 8-port PCI-E E1 card, wct4xxp 
driver. The symptom was choppy sound for all calls. The problem was 
resolved by disabling hyper-threading.

 From that moment on I always disable HT, to avoid problems.

I havn't seen your specific 12.5% cpu problem thought.

Maybe worth a shoot anyway?
