Boot attempts drop me into the dracut shell. I can't seem to access any of these files from there, so I booted the install DVD in rescue mode, then chroot /mnt/sysimage in order to access this information. dmesg contained information from booting the install dvd, so I had to retrieve some of the requested information from /var/log/messages Command line: Kernel command line: ro root=/dev/mapper/vg_hpoctane01-lv_root rd_LVM_LV=vg_hpoctane01/lv_root rd_LVM_LV=vg_hpoctane01/lv_swap rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=us # dmsetup ls --tree vg_hpoctane01-lv_home (253:2) \u251c\u2500 (105:2) \u2514\u2500 (104:1) vg_hpoctane01-lv_swap (253:3) \u2514\u2500 (105:2) vg_hpoctane01-lv_root (253:1) \u2514\u2500 (105:2) live-rw (253:0) \u251c\u2500 (7:2) \u2514\u2500 (7:1) # grep dracut /var/log/messages Nov 14 21:02:25 hp-octane-01 kernel: [ 5.160864] dracut: dracut-006-6.fc14 Nov 14 21:02:25 hp-octane-01 kernel: [ 5.170688] dracut: rd_NO_LUKS: removing cryptoluks activation Nov 14 21:02:25 hp-octane-01 kernel: [ 5.611227] dracut: Starting plymouth daemon Nov 14 21:02:25 hp-octane-01 kernel: [ 5.696859] dracut: rd_NO_DM: removing DM RAID activation Nov 14 21:02:25 hp-octane-01 kernel: [ 5.698311] dracut: rd_NO_MD: removing MD RAID activation Nov 14 21:02:25 hp-octane-01 kernel: [ 13.833090] dracut: Scanning devices for LVM logical volumes vg_hpoctane01/lv_root vg_hpoctane01/lv_swap Nov 14 21:02:25 hp-octane-01 kernel: [ 13.856448] dracut: inactive '/dev/vg_hpoctane01/lv_root' [50.00 GiB] inherit Nov 14 21:02:25 hp-octane-01 kernel: [ 13.860305] dracut: inactive '/dev/vg_hpoctane01/lv_swap' [64.00 GiB] inherit Nov 14 21:02:25 hp-octane-01 kernel: [ 13.864015] dracut: inactive '/dev/vg_hpoctane01/lv_home' [910.50 GiB] inherit Nov 14 21:02:25 hp-octane-01 kernel: [ 14.068027] dracut: Mounted root filesystem /dev/mapper/vg_hpoctane01-lv_root Nov 14 21:02:25 hp-octane-01 kernel: [ 14.125734] dracut: Loading SELinux policy Nov 14 21:02:25 hp-octane-01 kernel: [ 14.322449] dracut: /sbin/load_policy: Can't load policy: No such file or directory Nov 14 21:02:25 hp-octane-01 kernel: [ 14.541223] dracut: Switching root # cat fstab # # /etc/fstab # Created by anaconda on Thu Oct 21 14:43:02 2010 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/vg_hpoctane01-lv_root / ext4 defaults 1 1 UUID=7e12217c-db53-4985-b64e-24b6b188bf83 /boot ext4 defaults 1 2 /dev/mapper/vg_hpoctane01-lv_home /home ext4 defaults 1 2 /dev/mapper/vg_hpoctane01-lv_swap swap swap defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 curly.devel.redhat.com:/vol/engineering/devarchive/redhat /mnt/curly/redhat nfs defaults 0 0

I had the same error appear when I used a USB stick to boot Fedora 16. I happened on my atom powered netbook and my i5 powered PC. The fix for me was to run the program "Live usb Creator" as Administrator. I was using Windows 7 64 bit to create the bootable usb. Even though I was logged in as a account with administrative rights I needed to right click the program and select "run as administrator". Worked perfectly after that. Hope this helps or provides a clue.
Closing this, since the problem has gone away with updates and does not seem to be present in F17.
