We frequently get asked how to upgrade kernels, how to upgrade modules, etc.  This is actually in our knowledge-base, but I thought it would be useful to toss this onto the blog since we just pushed out a very important kernel upgrade, and want to make sure that this information is as accessible as possible!

1. Simply shutdown your VPS.  You must do a full shutdown and not a "reboot". 

2. Then, boot the machine from the management console.  IMPORTANT: If you have a 32-bit OS, you must use the command "boot32", this will be unnecessary in a future update.

3. Update your modules:

     wget -O - http://ftp.grokthis.net/pub/linux/modules/install_modules.sh | /bin/bash

4. You're done!  You might want to reboot if you depend on specific modules being available during boot.
