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) Pid: 1, comm: swapper Not tainted 2.6.38.6-26.rc1.fc15.x86_64 #1 Call trace: [<ffffffff8146c72c>] panic+0x91/0x19c [<ffffffff81b591f1>] mount_block_root+0x250/0x27b [<ffffffff81b593a2>] mount_root+0x53/0x57 [<ffffffff81b59513>] prepare_namespace+0x16d/0x1a6 [<ffffffff810742e3>] ? put_cred_rcu+0x0/0x8d [<ffffffff81b58edd>] kernel_init+0x2a2/0x2a7 [<ffffffff8100a9e4>] kernel_thread_helper+0x4/0x10 [<ffffffff81b58c3b>] ? kernel_init+0x0/0x2a7 [<ffffffff8100a9e0>] ? kernel_thread_helper+0x0/0x10
I saw this too. The reason was that I had lost my initrd line in grub.conf. The solution was to add it.
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?
