    Hallo,
        I have a Skymaster DTMU 100 USB tuner box with worked well with
        Linux when i was using Ubuntu 6.10 ( with kernel 2.6.17). It is
        recognized as a "Hanftek UMT-010 DVB-T USB2.0 with "Zarlink
        MT352 DVB-T" frontend. 
        Some Time ago i updated to Ubuntu 7.04 (kernel 2.6.20). Now i
        get an kernel oops when kaffeine scans for channels.This always
        happens at the Moment the "Lock" indicator goes on. I tried it
        with ubuntu Gutsy Gibbon (kernel 2.6.22) too and i still get
        this kernel oops.
        I tried the latest DVB drivers from Mercurial too. no change.
        
        Here is the relevant part of /var/log/kern.log :
