    Question Fedora Core 3 System Freezes (because of audio cd in hdc?)

    I am a technical person, but not a linux expert. My fedora core 3 machine frequently will completely lock up and the only solution is to power cycle. I have made many changes to my system since it was stable, most notably upgrading to the latest kernel, installing a RaLink wireless card, and reconfiguring yum. I have been through everything in /var/log and nothing jumped out at me. The only thing I noticed is the following message in root's mail for Log Watch. Any assistance on how I could start diagnosing or resolving the problem would be greatly appreciated.

    Linux shire 2.6.11-1.14_FC3 #1 Thu Apr 7 19:23:49 EDT 2005 i686 i686 i386 GNU/Linux

    Can you revert back to your old kernel?

    Does the system remain unstable when do you that?

    If it does, I'm going to guess you've got a harddrive about to fail

    What is hdc? Your CD drive? Or a HDD?

    hdc is my cd rom. I had a music cd in there, so I took it out. I hope that is not freaking out my system, if it is I might have a fun bug to report. I really don't want to rollback my kernel, because I had to recompile and reinstall my driver for my wireless card when I upgraded and don't want to go through that headache again. But that may still have to be my next step.

    I get those same hdc errors from my DVD drive and my system is rock solid. So I think that's probably a red herring.

    FWIW, here's what I'd try for starters:

    Reverting to an older kernel that was known to be stable like stry_cat said is a good idea, IMHO.

    But personally I'd worry most about that wireless card and its drivers. If you pull it out (pain, I know), is everything stable again?

    If no kernel is stable anymore, I'd boot from a Fedora install disk and run memtest through a pass or two, just to make sure your RAM (or CPU cooling) hasn't gone dodgey.

    If your hard drive is under suspicion, install smartmontools and run the smartd service (configure /etc/smartd.conf). Most drives are SMART-capable and should give some notice of imminent doom.

    Although the specific details of your problem are a bit different, I found that when I upgraded to 2.6.11-1.14, I encountered this bug https://bugzilla.redhat.com/bugzill...g.cgi?id=155472 which caused my system to freeze, most often during the poweroff cycle. I reverted to 2.6.11-1.7 and the problem went away. (I couldn't get 2.6.11-1.21 to work with my nvidia video drivers.)

    Try updating to the latest kernel using up2date. (kernel 2.6.11-1.27). I had encountered all sorts of problems with 1.14 and could not get my nvidia driver to work. I just updated from 2.6.9-1.667 to the 2.6.11-1.27 kernel, installed my nvidia driver and my system booted smooth as silk.

    Just upgraded my kernel the other day. Running 2.6.11-1.27_FC3. Still crappy.

    Day before yesterday I upgraded to kernel 2.6.11-1.27_FC3.x86_64 and the latest nvidia drivers (7176, I think). Nary a problem, and no hangs yet.
