Good morning, Hugh.

I can tell you that your problem is nowhere near unique.

I learned a long time ago not to blindly "upgrade everything" since it was sure to cause no end of problems eventually.

I have a fresh installation of FC6, and decided what the hell, may as well try a global upgrade and see what happens (after somebody in comp.os.linux.setup said something like "You're going to run yum -yt upgrade anyway, right?").

First of all, what is the "-t" switch to yum? I know "-y" tells yum to answer "yes" to everything, but I can't find "-t" in the man page. But, I digress...

Anyway, I tried a global yum upgrade of everything in my fresh FC6 installation, and after several hours, it hung pretty much the same as yours did. I rebooted, and cannot get the new kernel (2.6.20) to boot... gives me kernel errors.

So, I rebooted back to 2.6.18.

Now, I have absolutely NO idea what shape my installation is in, suspect it's not good at several levels, and I don't know what to do about it other than do a fresh re-install (which as I said this was a fresh install anyway so in THIS case that's not a big problem).

My problem for the future, though, is I have absolutely NO idea how to revert to a previous installation and remove the effects of a failed "yum -yt upgrade".

Can any of you direct me to some reading material that explains how to do that?

Otherwise, I don't dare upgrade or update much of anything, which for many reasons is not good policy...
