Fedora can't boot up after I install kernel-smp

[yinglcs]

Hi,

I have installed Fedora 5 on an external hard drive. It (2.6.15) works fine.
But after I installed 'kernel-smp' via yum, I can't boot up with the new kernel (2.6.20).

I get error message like this:

Unable to access resume device (LABEL=SWAP-sda4)
mount: could not find filesystem '/dev/root'
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
switchroot: mount failed: No such file or directory
Kernel panic - not syncing: Attempted to kill init!

I read this thread, but I am not sure how to resolve my problem:

Any idea is appreciated.

So the 2.6.15 works but the 2.6.20 doesn't. I haven't kept up with FC5, but there have been changes to udevd that *may* impact your problem.

First take a look in /boot/grub/grub.conf and make sure the arguments on the "kernel" lines
match for the working & nonworking. If that's not it then I'd verify that the /boot/initrd... for the new kernel was built when you installed the kernel. If not you may need to run mkinitrd again ,but check the /etc/modprobe.conf file first.

I think the problem is the transition to the new hd/sd renaming.
This post may shed some light on what is happening:

Thansk. I look at /boot/grub/grub.conf

They look the same:
title Fedora Core (2.6.20-1.2300.fc5smp)
root (hd0,0)
kernel /vmlinuz-2.6.20-1.2300.fc5smp ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.20-1.2300.fc5smp.img
title Fedora Core (2.6.15-1.2054_FC5)
root (hd0,0)
kernel /vmlinuz-2.6.15-1.2054_FC5 ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.15-1.2054_FC5.img

Hello:
When you installed the new kernel did you have the USB attached to the same machine as when you installed the 2.6.15 kernel ?
Or was the USB attached to a different machine when you installed the new kernel ?

I did have the external machine hookup to the same machine.

Any idea please, I am still not able to resolve my problem. I would like to take advantage of the dual core machine that I have.
thanks.
