Not likely gonna be cheap to run Linux on a CP. The CPs on the machine are likely kneecapped. And using them for Linux will probably drive up MSU costs on non-Linux systems. And you can't have a single Linux system use both an IFL and a kneecapped CP concurrently. So if it is a single Linux instance which is soaking the IFL, the only choice reasonable is another IFL.
