Description of problem: I have seen this issue on a Power Mac G4 "Digital Audio" and a Lombard Powerbook G3. The Apple sound in these systems isn't supported at boot time, but using modprobe to load snd-powermac (or using the GUI Soundcard Detection utility) will get the sound loaded and apparently working. However, after some time, the system will invariably crash hard, needing a hard reset. I am able to use a PCI Ensoniq sound card on my tower to avoid this issue, but this is obviously not available on the Power Book. Also, sound channels are not properly handled on the G4 Digital Audio. The internal speaker doesn't work until something is plugged into the Mac's sound-out port. Then the internal speaker will play sound, but no sound goes to whatever is plugged in. Version-Release number of selected component (if applicable): Fedora 7, Fedora 8. How reproducible: Always. Steps to Reproduce: 1. Boot system, update if necessary. 2. See that sound is not recognised. Use modprobe snd-powermac or the GUI util to load the sound modules. 3. Seems to crash whether the sound is in use or not - it just takes a little while. Wait it out. Actual results: System seems to work with sound modules loaded, but eventually crashes. Expected results: Firstly, I expect sound to work without use of modprobe. Secondly, of course, I expect the system not to crash. Additional info: This problem seemed to begin plaguing Fedora releases when udev was implemented. I'm fairly certain (though I will have to test FC 5 or FC 6 to be certain) that the hard crashes began in Fedora 7.
changing to component "kernel"

Was 2.6.23.1-49 tested? > I have freshly installed Fedora 8 and updated to kernel 2.6.23.1-49. While the module continues to fail to stay loaded at boot time (so that I have to use modprobe or the Soundcard Configuration GUI to load it), the system seems stable. I let it play music all day and it didn't crash.
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.
I don't know how to close it myself, but it might as well be. I think the crash was more a problem with that particular hardware. That system crashes like that in Mac OS X when compiling source code, oddly enough.
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
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.
