The problem is definitely not gnome or kde. The mount happens at boot time, right after udev. Also, the line I had in fstab was mounting a usb 250GB external hard drive. No CD or DVD drives involved.

I see the LVM find my logical volume (VolGrp00/LogVol00, or something similar), I see udev "start" (I can't remember the line in the start-up--I think it says "starting udev"), then I see an error saying the drive with a specific label can't be found. I can then provide the root password to get in and fix the problem. The drive with the label that can't be found is marked "noauto" in fstab. I've had it marked "auto" and everthing's worked for the past three months, but suddenly last night it stopped working so I tried "noauto" to skip the mount at boot time. The disk has the same, correct label--I checked. I switched back to "auto" and just commented out the whole line in fstab, rebooted the system to run level 3, uncommented the line in fstab and ran "mount -a" with no errors, so I know it's not the disk label. I suspect it's something with the disk device (/dev/sdb1, I believe) not being found. But why "noauto" doesn't prevent the device from being mounted at boot time is a mystery.

As I type this an idea to test just occurred to me, so I'll try it tonight when I get back to my office.
