I am facing this boot crash issue (along with several other people), and have failed to resolve this using various fixes/solutions available online(in numerous forums/blogs)
Kernel Panic - Not Syncing : Fatal exception in Interrupt
But my analysis have concluded that this is a kernel issue which happens with newer versions of ubuntu kernel 3.8.0-21+ versions and not a driver issue of GFX, broadcom, alsa etc
Question is can I use any other kernel with my ubuntu 13.04 like the main kernel or some alternative/custom kernel or install older versions of generic ubuntu kernel say 3.2 or 3.8.0.0 types
I use synaptic to install/remove kernels but the oldest version it shows to which i can downgrade to is 3.8.0.19 which also causes problems but frequency is less, with 3.8.0.26/27 it crashes everytime I boot.
