So you need to ensure that you unpack when you have the right 
number of fields:

either:

data = line.split()
if len(data) = 4:
      port, channel, lane, eyvt = data
else: continue
# rest of your code here...


or more pythonically:

try: 
     port, channel, lane, eyvt = line.split()
     # the rest of your code here
except ValueError: continue

HTH,
