Re: [Fedora-livecd-list] Kernel panic while booting from live cd

Hello all,
I have created a live cd with modified linux kernel using livecd-create tool. Just
installing the kernel rpm on the system using rpm -ivh works fine.
But when I try booting from the livecd, it gives the following error.
Just starting from the top, looks like possible problems with
device-mapper mirror support in the kernel/modules.
Try booting with cmdline changed from 'quiet' to 'verbose', and then
also try adding 'shell' or 'eshell'. If you make it to a shell, try
creating a devicemapper snapshot target manually and see if it works, or
try to figure out why it fails. Otherwise post the boot messages from a
verbose run.
cheers...
