lspci and dmesg output from SuSe on same hardware that fails LiveCD (deleted)

Description Domenick Rowe 2007-04-12 18:44:13 UTC
Description of problem:
I have an HP Pavillion zd8000. I currently have debian installed but am trying
to switch to FC. When I boot from the liveCD, I get this error message, a
request to create a symlink and then type exit to get out of the shell (even
though it seems the installation keeps trying to continue). I don't understand,
because it's booting from the CD, not the HDD. Please dumb the answer down a
bit--I'm a newcomer to linux (but not computers). If there's any additional
information needed to solve this, ask me here or via email at

Version-Release number of selected component (if applicable):
FC 6.92

How reproducible:
Every time

Steps to Reproduce:
1.boot from disc

Actual results:
system enters an endless loop after the error message...something with ata1.1
(if that means anything to you).

Expected results:
successful boot

Additional info:
I'll attach a bootlog file if it's helpful and someone tells me how.

if you could boot into your debian install and attach the output of 'lspci' and
'dmesg' that might give some clues.

lspci and dmesg output from SuSe on same hardware that fails LiveCD

I have been having the same problem (can't boot from LiveCD due to missing
/dev/root) since F7 Test 1, 2, 3, and now 4.  Attached is the output from lspci
and dmesg, as requested from the original poster.

I don't know if this is the best bug for me to add to but I just installed F7
from DVD and had the same problem. I've got a standard Intel ICH7 IDE
controller. I had to boot a rescue disk and fix references to a labeled root
partition in fstab and grub.conf. Booting by LABEL=/ was not working.

Hello Everyone,

I am helping a friend to install Fedora 8 on his laptop.

It is a HP pavilion dv9000 with Vista. After partitioning the disk with
qtparted, we installed FC8 x86_64 with no glitches.

On the first boot, we never get any joy because the system always gives us
/dev/root not found and stops with a kernel panic.

I have searched bugzilla and Fedora Forum for a solution, but I think this is
still a serious bug. Many people had this problem when FreeBSD was installed on
their drive, or had a RAID drive. But in this case, there are only four
partitions, two for Vista, one for linux root and one for linux swap.

I have tried turning off apic and apm in grub, but no joy.
I have tried booting the rescue disk and reinstalling GRUB, still no joy.
I have tried booting the rescue disk, doing a yum update, and rerunning mkinitrd
as suggested in other bug reports, still doesn't work.

I suspect there is something in the sata hard drive driver, however, I am
curious why the system boots fine using the install disk?

Thanks in advance.

One other point,

Changing root=/dev/sda3 from LABEL=/ did not work either.

Comment 7 Chuck Ebbert 2007-12-18 22:15:32 UTC
Problems with ALi controller (the original report) should be fixed by now.

Fedora 7 (and 8) respins are at
