From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; de; rv:1.8.1.8) Gecko/20071030 Fedora/2.0.0.8-2.fc8 Firefox/2.0.0.8 Description of problem: I've setup a server to run vdr with two Hauppauge NOVA-T DVB-T and two Terratec DVB-C cards. Both DVB-T cards are detected correctly, but only one of the DVB-C cards is found. I had all 4 cards working fine with F7 fully updated. The strange thing now ist that even lspci only shows one of the DVB-C cards. I have to use acpi=off and noapic as kernel options on this mainboard as the system otherwise freezes after some time. I'll attach the output of dmesg and lspci. Version-Release number of selected component (if applicable): kernel-2.6.23.1-49.fc8 How reproducible: Always Steps to Reproduce: 1. have two DVB-T (Hauppauge NOVA-T) and two DVB-C (Terratec) in the system 2. 3. Actual Results: Expected Results: Additional info:
Created attachment 254601 [details] output of dmesg
Created attachment 254611 [details] output of lspci -vvv
Can you also attach /proc/iomem and /proc/ioports?
Created attachment 256931 [details] contents of /proc/iomem

Possibly fixed in 2.6.23.8-63, please test.
Nothing changed with 2.6.23.8-63. Still only one DVB-C card is found.

Hello, I'm reviewing this bug as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug and will try and assist you in resolving it if I can. There hasn't been much activity on this bug for a while. Could you tell me if you are still having problems with the latest kernel? If the problem no longer exists then please close this bug or I'll do so in a few days if there is no additional information lodged.
The system is now on kernel-2.6.23.14-115.fc8 and the problem is still there. Only one out of two DVB-C cards is detected properly.
This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '8'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 8's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 8 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
In the meantime the system has been upgraded to a new mainbaord and F10. With the stock F10 kernel the problem is still there. Only one of two DVB-C cards is detected. Now the good news: Since kernel-2.6.27.5-117.fc10.x86_64 both cards are detected correctly. It would be interesting to know what was the cause of the problem.
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
