I get the below error message: VFS: cannot open device 3a:00 kernel panic: VFS: unable to mount root fs 3a:00 I took this from an archive message and it should be very close to the message I get except for the device number. I think mine says 1a:00 as I am only using ide and not scsi. The system locks up and I have to manually press the reset button to reboot. I have checked the archives but could not find a solution. Also the kernels I get from Redhat can boot just fine, but they have turned off my sound card so I need to regen the kernel.

Sorry your right that I should have included the boot loader, as it is grub. I am not sure what your wanting here, if it is a file or for me to discribe what I selected in the configuration. If it is a file please let me know what directory it is in and I will be happy to include it. I did select LVM and ext3 in the configuration. Thank you for your help, Sam.

I have had nothing but problems trying to get grub to boot a lvm root fs. I use lilo and have no problems at all. Below is the section of my lilo.conf. image = /boot/bzImage root = /dev/vg0/lv0 ramdisk = 8192 initrd = /boot/initrd-lvm-2.4.20-gaming-r5.gz label = shadow read-only I don't know about grub but in lilo I always had to give the ramdisk size.

I apologize if my advice has already been given and rejected. I experienced the exact same problem when installing a devfs capable kernel before installing the devfsd daemon. I use Debian, so I do not know where or how to find devfsd with redhat/RPM. Try installing devfsd and then rebooting one of the new kernels.
