all modules have stopped loading

Hello, I've run into some trouble and am having no luck finding an answer.
I'm running slack 12.0, and the other day I did an update with slackpkg. I did not update any kernel packages, and am still running stock kernel. I had slackpkg keep the old config files, and save the new ones with .new.

Now when I boot up, I see a lot of FATAL: Module X not found.
Once I login, lsmod shows no modules loaded. I've tried using modprobe to maunually add a module, and I get the FATAL not found message. depmod -V shows module-init-tools 3.2.2. I tried reinstalling the module-init-tools package from the install disc, with no luck. /etc/rc.d/rc.modules points to rc/modules-2.6.21.5-smp which is the kernel I am running.

I'm not sure of any other relevant info that might be need, but will list anything else that will help. Any ideas on what could prevent modules from loading like this?

Check your /lib/modules/$(uname -r) directory. It should exist. In a default installation, this is located in the kernel-modules-smp-2.6.21.5_smp-i686-2 package for the SMP kernel, and kernel-modules-2.6.21.5-i486-2 for the non-SMP kernel.

It looks like the modules are there, just not loading.
ls -l /lib/modules/$(uname -r) returns

Code:

What does `uname -r` output? (It should be 2.6.21.5-smp)
I think your problem is here:

Code:

-rw-r--r-- 1 root root 0 2008-06-05 17:28 modules.dep

Your modules.dep file is empty, and so no modules will load. You should run `depmod -a` as root to fix the problem. If that still doesn't fix the problem, you could try reinstalling the kernel-modules-smp-2.6.21.5_smp-i686-2 package (download it from your favourite mirror [or use the CD/DVD] and type `upgradepkg --reinstall kernel-modules-smp-2.6.21.5_smp-i686-2).

Great, depmod -a fixed it!
I'm not sure how that file got blanked.
Thank you very much for the help.
