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):
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.
What's the output of 'kudzu -p'?

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

output of lspci
Before booting the 2.6.13 kernel lspci showed the sound card. Afterwords it was
gone for all kernels.
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.
Yes, that did it.
