Hi, I have a problem. I installed FC3 on a Dell Optiplex GX 280 and everything works correcly. Now I use yum to update all packages (including the latest kernel). After updating I reboot and let grub select the newest kernel. After it starts I get the next error: mkrootdev :label /1 not found mount: error 2 mounting ext3 mount error 2 mounting none switchroot : mount failed: 22 umount /initrd/devfailed : 2 kernel panic - notsysncing: attempted to kill init. I need to use the power down button to shutdown the computer. I tried kernel Fedora Core (2.6.10-1.741-FC3smp) and Fedora Core (2.6.10-1.760_FC3smp) but both kernels gives the above errors. When I use the pre-installed kernel (out of the box) Fedora Core (2.69-1.667smp) kernel everything works alright. I googled but I can't find anything to solve this problem. Can anybody help?
