Hello,

I have a system freeze with linux kernel 4.5.3-1 if I use a tv card "leadtek DTV1000 T" ( Conexant CX22702 DVB-T )

I use the radeon driver, my graphic card is : amd radeon HD4650 pcie,

if I downgrade to kernel 4.5.2-1 then there is no freeze, all is ok

so I will try to do a git-bisect between kernel 4.5.2 and 4.5.3, in order to find the faulty commit,

an interesting news here, there is already a suspect :
