Hello,

I have Fedora Core 4 installed on my desktop and tried DVB-T tuner. However when trying to start play a tv station kernel freezes and I have to reboot the computer. I have tried several 2.6 kernels, but the same result.

What is weird is that I have the same configuration on my notebook and it runs ok with the same DVB-T.
The DVB-T is Yakumo QuickStick.

Here is output of dmesg:
dvb-usb: WideView WT-220U PenType Receiver (Typhoon/Freecom) successfully initialized and connected.

dvb-usb: recv bulk message failed: -110

Is there a problem in some dvb module?
