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 :
