I'm using a Gumstix with the Overo Stagecoach Board on Ubuntu 12.04 (though virtualbox). 
This time I tried to do a simple "sudo apt-get update" and I got another kernel panic with the error:

root@linaro-alip:~/ros# sudo apt-get update

Hi Qandeel, can you share some details, such as your hardware setup and the output of kernel panic?

Thanks!

I downloaded the pre-built image of Linaro with ROS from the Gumstix website and then when I try to use ros and run roscore, it runs in to a kernel panic and then hangs.
I don't understand why or how to stop it.
