ok - so I am getting the kernel panic in my (kickstart PXE invironment). I have used this environment since cents 5.2 The PXE starts up 5.6 gets installed that all works fine. then after it reboots I get the kernel panic cant mount root (0,0) This is just one disk SATA nothing special. Same hardware I have always used. I not have booted into rescue mode. my /etc/grub.conf looks fine. everything else looks fine. I have tried 3 different machines now. All three get the same result. I have not changed anything in my kickstart environment from 5.5 to 5.6 other than change numbers from 5.5 to 5.6. What am I looking for? as I mentioned grub looks fine. Thanks, Jerry
