Description Jure Repinc 2011-06-13 19:44:50 UTC 
Description of problem:
I've downloaded the 64-bit Fedora 15 live CD with KDE software and dd-ed it to my USB key. I used the USB key to boot to desktop (works just fine, I'm writing from it now). At the end I started the "Install to Hard Drive" and installed Fedora on 4th primary partition, formatted as EXT4. All appeared to go fine and then finished and I rebooted the system. After some seconds of countdown the system should boot up bit instead I got a kernel panic.

Version-Release number of selected component (if applicable):
64-bit Fedora 15 KDE LiveCD

How reproducible:
Always

Steps to Reproduce:
1. used the dd to put ISO to USB drive
2. booted from USB drive
3. started installation app
4. rebooted the computer
  
Actual results:
Kernel panic on boot

Expected results:
System should boot just fine

Additional info:
The hardware is:
* ASUS P8H67 motherboard with BIOS 1003
* Intel Core i5 2500K CPU
* Maxtor 6L25050 hard drive
* ATI Radeon HD 5750 graphics card
* 8 GiB of memory

This is what I see when the kernel apnic happens:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Comment 5 Mads Kiilerich 2011-07-25 14:11:44 UTC 
I saw this too.
The reason was that I had lost my initrd line in grub.conf.
The solution was to add it.
Comment 6 Josh Boyer 2011-09-27 16:05:18 UTC 
Can you see if Mads' comment is triggering the oops in comment #4, and if not does this still happen with the 2.6.40.x F15 kernels?
