Description Zach Anderson 2005-10-18 20:11:34 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050922 Fedora/1.0.7-1.1.fc4 Firefox/1.0.7

Description of problem:
Recently did a yum update that pulled down kernel-2.6.13-1.1526_FC4. Subsequently kudzu no longer detects my Intel AC'97 Audio Controller. Instead it finds an Intel AC'97 Modem Controller, which it hadn't before.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Update kernel
2. Run kudzu
3. Notice that AC'97 Audio Controller is nowhere to be found.

Actual Results:  The audio controller is not detected. There is no entry for it in /etc/sysconfig/hwconf, and it is not mentioned in doing an lspci.

Expected Results:  Kudzu should have found the device.

That's odd. lspci output? Does the lspci output change if you boot a different

Comment 5 Zach Anderson 2005-10-18 22:28:47 EDT
Before booting the 2.6.13 kernel lspci showed the sound card. Afterwords it was
gone for all kernels.
Comment 6 Bill Nottingham 2005-10-19 14:00:38 EDT
Assigning to the kernel, then. Please attach /var/log/dmesg from the boot of a
later kernel so we can see the PCI messages from bootup.

2.6.14-1.1637_FC4 has been released as an update for FC4.
Please retest with this update, as a large amount of code has been changed in
this release, which may have fixed your problem.

Thank you.

Yes, that did it.
