I have a CentOS 4.2 system that had a bad CD-ROM drive. Every time I inserted a CD, the system would hang (no kernel panic, but no response to mouse, keyboard, or even the network - all I could do was hit the reset button). Today I replaced the CD-ROM drive with another I had lying around. The new drive is a 24x10x40 CD-RW. I don't know the exact model of the motherboard (I should have looked while I had the case open earlier this afternoon), but I know it's an Intel desktop motherboard that's at least 5 years old with a 1.7 GHz Pentium 4. Anyway, to make a long story short, now the system won't even boot! Here are the last few lines on the screen: Starting udev: [ OK ] Initializing hardware... storage network audio done [ OK ] Kernel panic - not syncing: drivers/ide/pci/piix.c:394: spin_lock (drivers/ide/ide.c:c037bb68) already locked by drivers/ide/ide-iops.c/ 1234 Any ideas how I can work around this? I've booted from the CentOS 4.2 CD #1 into rescue mode, but I don't know what I should look for next. Other than removing the CD-ROM drive, what can I do to fix this problem? Thanks in advance for any help, Alfred

So, is this CD-ROM drive just not compatible with my motherboard? If so, is there a way to make it compatible (i.e., some jumper settings)? If more details are needed, I can disconnect the computer again, remove it from under the desk (not an easy place to get to), and get the motherboard and CD-ROM drive details. I really want to get this to work. For now, I can live without the CD-ROM. If I need to go an buy a new (compatible) CD-ROM drive, that's OK. I just need to know what I'm looking for. Thanks, Alfred
