Hi all,

I updated my Fedora Core 6 system today with yum, including a kernel update to kernel 2.6.20-1.2925.fc6 (from version 2.6.19-1.2911.6.5.fc6) and my HD-5500 had some issues. The /dev/dvb/ directory was missing completely, and my previously working mythtv digital setup could not find the card, although /dev/video0 was present and tvtime worked perfectly. Rebooting back into kernel 2.6.19-1.2911.6.5.fc6 resolved the problem. A quick google search revealed that at least one other person had exactly the same problem (though no solution). I'm not sure how to diagnose the problem, but I thought I would drop a heads up to those running FC6. I'd be happy to boot back into 2.6.20-1.2925.fc6 to gather more information if anyone has any suggestions as to how I might troubleshoot the situation. Otherwise I will stay with 2.6.19-1.2911.6.5.fc6 for now.


Cheers,

P.S. Thanks for sifting through all the spam to read this!

I posted this in another section

the dvb kernel module isn't loading correctly

/sbin/insmod cx88-dvb

should kickstart it

Thanks. Although for some reason 'insmod cx88-dvb' didn't work for me, giving me the error:

insmod: can't read 'cx88-dvb': No such file or directory

but 'modprobe cx88-dvb' did work.

Incidentally, kernel 2.6.20-1.2933.fc6 which I tried today also has the same problem.

Cheers,

I originally had modprobe, but I changed it during a massive surge of doubt. That's what I get for posting from a Windows machine where I can't double check myself!

Glad it worked out.

Is the cx88_dvb module now loading on boot?

This used to be a problem in earlier versions of Fedora. I thought that it had been fixed, but it may once again be rearing it's ugly head.

Here's a link to an old post that describes how to correct that in FC4, I don't know if the same fix will work with FC6:

Edit the modules.pcimap file as recommended.

This appears to be resolved with the update to 2.6.20-1.2944.fc6.

Thanks again...
