I've used Dirk Westfal's article which describes how to create a Fedora 4 livecd, to create my own customized livecd: http://fedoranews.org/mediawiki/index.php/Creating_a_Fedora_Core_4_LiveCD I've tried to use the HOWTO and RPMs to create fedora based livecd (console mode only). I've installed FC6, and now, I try to make the Livecd again. With kernel 2.6.17-12187_FC5, all works fine, also on a FC6 install. However, with the latest 2.6.19 fc6 kernel, I get the following error messages when booting from this kernel? RAMDISK: ext2 filesystem found at block0 RAMDISK: Loading 8000KiB (1 disk) into ramdisk... done. EXT2-fs: blocksize too small for device grow_buffers: requested out-of-range block 18446744071562067968 for device ram0 isofs_foll_super: bread failed, dev=ram0, iso_blknum=17, block=-2147483648 No filesystem could mount root, tried: ext2 iso9660 Kernel panic - not syncing Do you have any ideas what I have to change to get this kernel booting? I suppose the important message is: EXT2-fs: blocksize too small for device, but I don't understand why the 2.6.17 boots and 2.6.19 doesn't. Lars
