The latest version of mkinitrd for Fedora 10 is 6.0.52. How did you get 6.0.71, or at least parts of it, installed?
Comment 2 Nivag 2009-02-19 19:10:43 EST
I did nothing explicit to install a new version of mkinitrd, I think it must have come as part of a regular yum update.

I did 
    grep mkinitrd /var/log/yum.log
and got:
    Jan 09 23:35:15 Updated: mkinitrd-6.0.71-3.fc10.x86_64
(I'm in New Zealand, which is currently 13 hours ahead of GMT.)

Is there a safe way to revert to 6.0.52, this is the main box in the house and the gateway to the Internet, so my life would not be worth living if I stuffed it up...  <worried grin>
Comment 3 Nivag 2009-02-19 19:32:20 EST
I note that 
    mkinitrd-6.0.71-3.fc10.x86_64.rpm. . . . . . Dec 22 19:28.

Also that
    mkinitrd-6.0.71-2.fc10.x86_64.rpm. . . . . . . . . . . . . . . . Nov 12 23:34 

I don't know which mirror yum used originally.
Comment 4 Chuck Ebbert 2009-02-20 02:01:10 EST
Sorry, I must have been looking at Fedora 9... I think this is a bug in mkinitrd and/or nash?

Is the package nash-6.0.71-3 installed, and is the file 
/usr/lib64/libnash.so.6.0.71 on disk?
Comment 5 Hans de Goede 2009-02-20 02:41:21 EST
This feels very familiar to a same problem we've been seeing with libparted missing from the initrd.

Can you please do:
ls -l /lib64/libnash*
ls -l /usr/lib64/libnash*

And paste the output here?
Comment 6 Nivag 2009-02-20 03:23:32 EST
# ll /lib64/libnash*
ls: cannot access /lib64/libnash*: No such file or directory

# ll /usr/lib64/libnash*
-rwxr-xr-x 1 root root 125496 2008-12-09 07:44 /usr/lib64/libnash.so.6.0.71*

# alias ll
alias ll='ls -lF'

# locate libnash

(/bulk/neptune-20090216-usr is a backup directory of my son's machine 'neptune', my machine is 'jupiter')

I installed Fedora 10 this year, and the only update is to mkinitrd-6.0.71-3, hence the Jan 09 date of the yum update log.
Comment 7 Hans de Goede 2009-02-22 09:22:32 EST
Nivag, can you try regenerating the trouble some mkinitrd like this:

mkinitrd -f /boot/initrd-$(KERNVER).img $(KERNVER)

And thry booting the new kernel again? If that does not work can you try again with selinux out of the way:

setenforce 0
mkinitrd -f /boot/initrd-$(KERNVER).img $(KERNVER)

Note that the #### in the KERNVER= line needs to be filled in by you, do an ls /boot to see what it should be.
Comment 8 Nivag 2009-02-22 14:50:04 EST
I used the following commands:

export KERNVER=-
mkinitrd -f /boot/initrd-$KERNVER.img $KERNVER

rebooted (shutdown -r now)
selected kernel
reboot halted after 
    Starting smartd
reran my NVidia driver creation procedure

selected kernel
got into my GNOME session

I'm now typing this...

N.B. I had to remove the round brackets from 
   mkinitrd -f /boot/initrd-$(KERNVER).img $(KERNVER)
not sure if the 'export' was required, but it is my normal practice


Curious, this work around is new to me, why was it necessary this time?  I normally upgrade to the latest kernel from yum as soon as it is available.
Comment 9 Nivag 2009-02-22 14:57:12 EST
Note that I run with SELinux Disabled - had too many problems with it on my box.

So I can't comment on whether your selinux commands may be required in some situations.

Yes and that should work just fine, you hit some sort of glitch, what you did is *exactly* the same as what the kernels post install script does. Weird!

I'm going to close this, but I'll keep an eye out to similar bugs.
