I did some testings with different mantis versions and found the  
changeset which introduced the freeze-while-tuning-bug:

b7b8a2a81f3e    Failed tuning
...
f5b1f9d491bf    Failed tuning
08f27ef99d74    OK
822c8b267e86    Compile error *1
8fb2812f8342    Compile error *1
f348cfa56c7a    OK

Changeset "f5b1f9d491bf" (Implement HIF Mem Read/Write operations) broke it.

*1 mantis-*/v4l/mantis_dvb.c:193: error: implicit declaration of  
function 'mantis_ca_init'
