Description Brandon Mayes 2008-04-04 11:09:26 EDT

User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv: Gecko/20080325 Fedora/ Firefox/

Description of problem:
This appears to be the same behavior reported in a Fedora Core 2 bug report:

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:

 1 NTFS partition running Windows XP

 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 \
5. update menu.lst with the following information:

title           Fedora 8 (Werewolf)
root            (hd1,0)
kernel          /boot/vmlinuz- root=/dev/sdb1 rhgb quiet
initrd          /boot/initrd-

6. reboot and now the kernel loads

Version-Release number of selected component (if applicable):

How reproducible:

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

Additional info:
Here is some information about my system's hardware:

CPU:  Athlon64 3800+
HARD DISKS:  2 SATA-II (3 Gbps) drives
GRAPHICS:  Nvidia 7600GT (by EVGA)

Is this still a problem in F9 Preview?
Comment 2 Brandon Mayes 2008-04-25 09:20:32 EDT
I installed F9 preview and I tried to test it out.  Again, the installer
completed just fine but when I went to boot it, all I receive is this:

Error 2: Bad file or directory type

Press any key to continue...

Pressing a key returns me to the grub menu where I can load Ubuntu or Windows XP
just fine.  I am still trying to figure out how to fix this.  I have tried
numerous changes to menu.lst and none of them seem to make a difference, though
I'm honestly not even sure if this is related to menu.lst settings.

Once I get this fixed (hopefully I can), I will post with more information about
this particular bug report.
Comment 3 Brandon Mayes 2008-05-03 15:49:30 EDT
I have been able to successfully figure out the "Bad file or directory type"
issue from my previous comment.  It is caused by bug 443289.

I went ahead and installed Fedora 9 preview x86_64 (and let it write grub to the
MBR this time to avoid bug 443289) using the live DVD.  I was able to
successfully boot without needing to make a new initrd, so it appears this issue
has been resolved in F9.  I believe this bug can be closed at this point.
