Hi,

there will always be combos of FW/drv version that will/not work. this 
can change over time back and fwd between stock and -ct code bases. -ct 
has been opt-in since it was merged. It would be uch better to figure 
out which FW works and why the driver dies. Otherwise we'll start 
flipping back and fwd between stock/-ct versions with each update on 
each wmac silicon / arch combo constantly.
