I was running my virtualbox-ose after upgrading to the latest 2.6.24-23-generic kernel and I got an error message that the kernel didn’t contain the correct modules for virtualbox. So being as virtualbox-crafty as I have become recently I thought, “HA, i got your kernel doesnt contain the correct modules right here buddy!”

I purged recent memory and thought back to when I tried to setup a VPN on winxp in a virtualbox-ose guest machine… It finally came to me:

sudo /etc/init.d/vboxdrv restart > i typed
* Starting VirtualBox kernel module vboxdrv [ OK ]
* Kernel Modules not loaded (or something similar) [ OK ] > terminal replied!

Damnit, I can fix this I thought… Using tab completion and apt-get i found the following possible command and ran it:

sudo apt-get install virtualbox-ose-modules-2.6.24-23-386

Bad idea

From then on, my machine was booting into the 2.6.24-23-386 kernel and my sound and wifi no longer worked… Not what I wanted. Well since I didn’t know I created a problem until today, I finished my Music on Hold project for the NorVergence Matrix CCS / ESI 42s I was working on within fruity loops 5 without the ability to hear the changes I was making, and got around to resolving the sound issues earlier tonight.

To fix the problem I pressed escape during the grub loader init and selected the 2.6.24-23-generic kernel. Once up and running I ran…

sudo apt-get remove linux-headers-2.6.24-23-386

It err’d out at the end stating that /etc/src/linux-headers-2.6.24-23-386 could not be removed because files still exist in the directory. So I did the following…

cd /etc/src/linux-headers-2.6.24-23-386
ls -al

I noted that the only file left was a “.lst” file. So I…

sudo chmod 777 .lst
sudo rm .lst
cd ..
sudo rmdir linux-headers-2.6.24-23-386

Which is all fine and great and all… but before I realized I could boot into the 24-23-generic kernel I messed around trying to recompile my ieee80211, ipw2200, and wireless-utils packages in attempt to fix the problem. At least now my sound works…

-Update 9:15pm-
Fixed my wifi… turns out that I killed the wifi radio with fn+f2 at some point and forgot to turn it back on. Since the wifi light on my Inspiron 9300 doesnt turn on under ubuntu, I hadn’t the faintest idea that it was turned off until I ran sudo iwconfig and noted that it said that the radio was off on eth1.
