Eric,

	This can happen if the zaptel drivers are not properly modprobe -r'd 
before the system is shutdown.  It has been mentioned on the wiki 
before.  Try bringing up the system, modprobe'ing the modules, modprobe 
-r'ing them, and reboot.  Then modprobe the modules and check the 
interrupts.  What kind of mobo/chipset is this?
