From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem: After updating to kernel-2.6.10-1.741_FC3 from kernel-2.6.10-1.737_FC3 alsa is no longer working. amixer gives the error: amixer: Control default cinfo error: No such file or directory The loaded modules are snd_ntel8x0m and snd_intel8x0. The following items are missing from the /proc/asound directory (that are there with kernel 2.6.10-1.737_FC3) /proc/asound/ICH@ /proc/asound/card0/pcm1c/ and all of /proc/asound/card1 and its contents. Version-Release number of selected component (if applicable): kernel-2.6.10-1.741_FC3 How reproducible: Always Steps to Reproduce: 1.boot with kernel-2.6.10-1.741_FC3 2. load modules snd_intel8x0m and snd_intel8x0 3. Actual Results: Missing items in /proc/asound as detailed above and sound and modem do not work. Expected Results: Fully populated /proc/asound and sound and modem work. Reverting to kernel kernel-2.6.10-1.737_FC3 restores expected behaviour. Additional info:
Resolution: after the upgrade to kernel-2.6.10-1.741_FC3 the following line in modprobe.conf causes loading the module intel8x0.ko to fail: options snd-intel8x0 index=0 id="ICH" Removing this line from modprobe.conf resolves the problem.
