Bug Description
Binary package hint: linux-source-2.6.20
When i do a Channel-Scan with Kaffeine, the application freezes and I get a Kernel Oops.
I have a Skymaster DTMU 100 DVB-T Device with an USB Interface.
It is detected as Hanftek UMT-010 DVB-T USB2.0 by the kernel an uses the kernel-module dvb_usb_umt_010
With Ubuntu 6.10 everything worked fine.
part from kernel.log :

Thanks for taking the time to report this bug and helping to make Ubuntu better. With which specific version of the kernel did you notice this bug? You can check via 'cat /proc/version_ signature' . Additionally is this an issue with the latest version of the kernel for Feisty? Thanks in advance.
