Description Bernd Bartmann 2005-05-11 15:13:36 EDT

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050416 Fedora/1.0.3-1.3.1 Firefox/1.0.3

Description of problem:
I'm trying to get the newer Hauppauge Nova-T DVB-T card with CX88 chipset to run under FC4 Test3. Thankfully this module is now finally enabled in the kernel config. FC4 autoloads a lot of DVB and CX88 modules but not the cx88-dvb module. When I manually try to load cx88-dvb the system locks hard and gives a kernel call trace. I'll try to capture a trace via serial port later.

BTW: My system also has a Cinergy 1200-C card in it the works just
fine out of the box with FC4 Test3.

Comment 2 Bernd Bartmann 2005-05-14 12:16:15 EDT

Upgrading to 2.6.11-1.1305_FC4 fixed the problem. Looks like the proper fix is
in 2.6.12-rc4.
