My guess would be that you have a hardware issue.  Either a bad piece of 
hardware or a hardware compatibility issue.  Check the output of "cat 
/proc/interrupts" to make sure you don't have any IRQ sharing.  I have 
personally not had good luck with Digium analog cards, but most people 
seem to use then without issue.
