Public bug reported:
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 :
