I hope it works.
You use a livecd and in the terminal:
/dev/sda1 = / (your linux, as appropriate)
Example:
fsck /dev/sda1
mount /dev/sda1 /media/linux
chroot /media/linux
source /etc/profile
And change the password:
passwd
There is another way you can do in the event that the above does not work,
change the kernel version and so on ...
grub edit> kernel /vmlinuz-2.6.9.42.ELsmp ro root=LABEL=/ rhgb quiet 1
Press Enter, and the B, mode single-kernel boot. Once we can use the
passwd command to change the password for the root.
Passwd #
Enter new UNIX password:

Hello, Friendly Fedora Folks:
My problem seems possibly related to some recently reported issues,
but I'm unable to fit suggested solutions to my issue. Anyway, here
goes:
I have an Asus EeePC 900A. It predictably took me about 2.5 minutes to
figure out that I wanted nothing at all to do with the crummy Linux
distro that came with it. I wanted Fedora and thought I'd try out the
Omega spin that Rahul announced recently.
Now the 900A has only a 4GB flash chip for internal storage, so I
started thinking of ways to reduce writes to the filesystem. It seemed
to me that ext2 was a better fit than ext3 because there would be no
need to write the journal data. During the install from LiveCD, I
chose to format the entire 4GB as ext2 and mount it on /. No separate
/boot partition, no swap partition.
After install, I discovered that the root filesystem was ext3 despite
my explicit instruction to format it as ext2. I consider that a bug,
which I might pursue if I can get past my current predicament.
I figured that "downgrading" to ext2 would not be difficult. So I
changed ext3 to ext2 in fstab and added noatime to the options.
Everything seems good at this point. I reboot, and mount tells me that
the root filesystem is, indeed, ext2. After running through the
installed packages and removing several that I thought would never be
relevant to my limited hardware, I rebooted again and found everything
good.
Well, almost everything. It turns out that now I can yum update
everything except for the kernel. After kernel update, I can't log in
at all. I get to the gdm screen, enter username and password, and it
just returns immediately to a fresh gdm screen. If I boot to runlevel
3, I have a similar symptom in text -- entering username and password
just returns to the login prompt.
At this point, I'm stuck. I've tried everything I know (not much) and
I can't log in. I did take a snapshot of the system with dd just
before upgrading the kernel, so I can always bring that back. But then
I can never apply any kernel updates.
Help!
