Kernel panic minutes after suspend

After resuming from a suspend, I will experience a kernel panic.
This can be reproduced every time by doing the following steps:
1. Suspend to Ram.
2. Press a key to wake it up.
3. On a console type "sudo apt-get install mc".
4. The package will download correctly, but as soon as it attempts to install it will cause a kernel panic.

These steps are just a way to consistently reproduce the issue on my laptop, it will usually happen after surfing around on the Internet.

I am using Kubuntu 9.04 64 bit fresh install, and I have added:
linux-backports-modules-2.6.28-11-generic-2.6.28-11.12(amd64)
I am using a wireless WEP Hex encryption.
