Bug 440703

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8.1.13) Gecko/20080325 Fedora/2.0.0.13-1.fc8 Firefox/2.0.0.13

Description of problem:
This appears to be the same behavior reported in a Fedora Core 2 bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=126953


I installed Fedora 8 x86_64 on a newly added SATA-II drive in my system.  The installation process went fine, but when the computer rebooted, Fedora 8 would not load.  Instead, it kernel panics and I get this message:

VFS: Cannot open root device "sdb1" or unknown-block(0,0)
Please append a correct "root=" boot option; here are the available partitions:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)



My drives are partitioned as follows:

/dev/sda:
 1 NTFS partition running Windows XP

/dev/sdb:
 sdb1: ext3 for Fedora 8
 sdb2: 1GB swap
 sdb3: ext3 for Ubuntu
 sdb4: NTFS "data" partition


I was able to work around the problem by using the suggestion in the above:

1. reboot with the Fedora 8 DVD in the drive
2. enter the recovery mode
3. chroot /mnt/sysimage
4. mkinitrd --preload=scsi_mod --preload=sd_mod --with=ata_piix \
             /boot/initrd-2.6.23.1-42.fc8.img-sata 2.6.23.1-42.fc8
5. update menu.lst with the following information:

title           Fedora 8 (Werewolf)
root            (hd1,0)
kernel          /boot/vmlinuz-2.6.23.1-42.fc8 root=/dev/sdb1 rhgb quiet
initrd          /boot/initrd-2.6.23.1-42.fc8.img-sata
savedefault
boot

6. reboot and now the kernel loads

Version-Release number of selected component (if applicable):
kernel-2.6.23.1-42.fc8

How reproducible:
Always


Steps to Reproduce:
1. Install Fedora8 x86_64
2. Reboot after installer has finished and kernel will panic

Actual Results:
Kernel panic; Fedora 8 never finishes startup

Expected Results:
Fedora 8 should load
