Created attachment 843823 [details] top half of screen after panic Description of problem: kernel panic on boot Version-Release number of selected component (if applicable): kernel-3.12.5-200.fc19.x86_64 How reproducible: boot kernel Steps to Reproduce: 1.boot kernel 2. 3. Actual results: kernel panic. The screen scrolls beyond the beginning of the panic. I'm attaching screen shots of what does show on the console. It's too early in boot for any logging. Expected results: boot Additional info: I've just upgraded to 19 from 18. kernel-3.11.10-100.fc18.x86_64 boots without problems. I've attached two jpeg's of the screen after the panic.

Hi Sean, the panic happens in init/do_mounts.c:mount_block_root() and is explicitely forced by the kernel because it has not been able to find the specified root (UUID=0ee4b2cd-0143-4172-9d7f-c1bef74a1150): panic("VFS: Unable to mount root fs on %s", b); This can happen for different reasons. My first thought would be that the initrd file is missing some driver or has some other issues (although other causes are certainly possible). Could you attach /boot/grub2/grub.cfg and the initrd file under /boot corresponding to the 3.12.5 kernel? Thanks, Michele
You put me on the right path: initramfs-3.12.5-200.fc19.x86_64.img was not installed. I reinstalled the kernel, and all is well. It seems there was some error by fedup on the upgrade. Thanks for the help. sean
