Add a printk to SetPIDs() (av7110.c) and verify that the pids are set to 
zero when there is no signal. av7110_before_after_tune() calls 
SetPIDs(0,0,0,0,0) if the frontend looses signal.
AFAIK this code was added to avoid arm crashes...

The 1.3. has a different frontend chip.
I tested my Rev. 2.1 Nexus (stv0299-based) without sat signal: It did 
not crash within several hours. How long does it take in your setup 
until the arm crashes?
