Try re-updating, maybe something got messed up since that appears to be the only difference (different times).

Cool

Well you could do that too, though be prepared for a long hard night

Nah, instead I'd suggest removing the kernel that got updated (not the working one!) and then try updating again.

Cool

First you'll need to know the package name that got installed, so as root in a terminal type:
rpm -qa | grep kernel
And you'll likely see quite a few packages. Try to find the one(s) that match the upgraded kernel, then type (make sure you are picking the correct kernel, not the working one):
rpm -e packagename
Where packagename is the package you find from the command above.

Cool

That's really beyond me, however I'm assuming (bad idea sometimes ) that RedHat uses RPM's to upgrade. If that's so, then the command:
rpm -qa | grep kernel
Should list the package name that got upgraded. You just have to compare it to the kernel that doesn't work to make sure it's that one and not the working one.

Cool

if you haven't already "rpm -e"-ed the kernel upgrade ...

It seems your your 2.4.20-19.9 kernel is unable to find the root device.

Have a look into your lilo.conf or grub.conf.

can do rpm -e --test kernel-2.4.20-8 to be rest assured.

You *may* also have the old kernel-doc and kernel-source.

Hey guys, I'm sorta new to Linux, i've been using red hat for years, but on and off, never really was good at it

I have this exact same problem, i tried rpm -e kernelblahblah and reinstalling it but I still get the error.

Quote:
Have a look into your lilo.conf or grub.conf.
What exactly would i look for to change and what to change it to?

Any help is appreciated.
