Description of problem:
Well I just booted the LiveCD and then this error is on the screen:

WARNING: Cannot create root file system!
http://img374.imageshack.us/img374/7828/rimg0172ax6.jpg (Screenshot)

I tried both boot parameters (the 1GB+ one and without - I have 1GB RAM "-" 128MB for the graphic card), but nothing changed.
And of course I checked the sha-sum and it was the same I found on the ftp-server!

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

How reproducible:

Steps to Reproduce:
1. Boot the LiveCD
2. Wait

Actual Results:
This screen...

Expected Results:
Fedora "Live"

Additional info:

Comment 1 Guido Ledermann 2007-02-10 20:47:55 UTC
Same here. Maybe it has something to do, that I only have SATA disks in use?

Comment 2 Sebastian Vahl 2007-02-28 20:03:48 UTC
Same problem (no /dev/root) here with F7test1 on two machines:

1. http://smolt.fedoraproject.org/show?UUID=e689326b-2c7d-4fbc-969e-f6293086ab97
2. http://smolt.fedoraproject.org/show?UUID=2e386ff4-8c36-4017-bae0-deab54df7e77

Also a self created livecd with livecd-tools based on todays rawhide stopped at
the same point. The rawhide installation itself boots fine.

Not sure if its relevant: I've also extracted the livecd-initramfs.img from the
live-cd. There ist no pata_via and ata_generic. When the boot stops the only
loaded modules are: ehci_hdc and uhci_hcd.

Comment 3 Jeremy Katz 2007-03-01 19:21:26 UTC
test2 should be a lot better here.  We were missing a few (important) modules
due to typos in the module list.

Can you try again with test2?

On my hardware test2 is booting fine.

Comment 5 Richard Körber 2007-03-01 21:57:11 UTC
Both F7 test 1 and F7 test 2 Live CDs are failing on my machine. :(

Comment 6 Bill Nottingham 2007-03-02 17:29:33 UTC
Moving to 'devel' as discussed on

Sure! And now it works fine on my machine (too).

Is it exactly the same error? It seems to me, that the bug is fixed with test2
(in regard with my experiences and Mr. Vahl's)...

It is exactly the same error. I will attach a screenshot.

The machine is:

Error messages returned by test2 livecd, before the warning

I just realized that test2 version of the livecd returns something before the
warning. Hope it helps.
Again, the machine is

Comment 13 Jeremy Katz 2007-03-20 15:28:25 UTC
For the cases which are still failing, can you look in /sys/block when you get
dropped into the shell and see what's there?  Also, what's in /proc/modules?

(In reply to comment #14)

Hmmm, so that looks like the block device is there and getting found.  What's
the output of /lib/udev/vol_id -l /dev/sr0?

Comment 16 Richard Körber 2007-03-20 20:18:44 UTC
Well... I can ls the /dev/sr0. But when I invoke the vol_id command, I am
getting an endless (I assume) output of "ata2.00: qc timeout" errors. I just
turned off the power after a couple of minutes since there seemed to be no
ending and also no way to abort it.

A screenshot will follow...

In my /sys/block I have
ram0 ram10 ram12 ram14 ram2 ram4 ram6 ram8
ram1 ram11 ram13 ram15 ram3 ram5 ram7 ram9

and after this output it start a sequence of "ata2: port failed to respond"
messages (this time endless, I have to reboot). I tried to list the content of
/proc/modules but the sequence of error message started as soon as I tried to cd
to /proc.
I'll try again and post the results.

Comment 19 Jeremy Katz 2007-03-20 20:41:22 UTC
Okay -- Saverio and Richard, your problems both look like problems with the
kernel recognizing and working (respectively) with your CD drives.

I hate asking this, but can you file separate bugs against the kernel so that
they can be tracked properly.  You've got different hardware and slightly
different symptoms and so it would be a lot easier if we could track them

Closing this out as the original reporter's bug has been resolved

Comment 20 Richard Körber 2007-03-20 21:05:00 UTC
For reference: I have opened Bug 233202. Thanks for your help, Jeremy.
