Unfortunately the issue was due to old hardware. I believe the CPU was faulty and it caused lot of problem with booting. Even after booting, the system fails unexpectedly.
I upgraded my hardware recently and didn't have any problem after that. So, we can mark this as resolved for now. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1173458 Title: system hung while booting Status in “linux” package in Ubuntu: Confirmed Bug description: I just upgraded to Ubuntu 13.04.
