I recently installed Ubuntu 12.04 LTS on my SONY VAIO VPCEH (with Windows 7 Home Basic

previously installed). Sometimes when I boot in Ubuntu, following things happen:

Ubuntu loading screen seems to freeze.

Esc key doesn't show installation progress.

Hard-drive led doesn't glow.

caps lock and scroll lock keys keep blinking.

I've to manually restart my laptop. On restart, Ubuntu loads normally.

What can I do to recover from present situation?

This sounds like a IRQ Conflict Problem. But could also be a kernel Panic Problem. You should try to add some boot parameters and check if they might help. You can add those to the grub menu.

I sometimes had to use the following: (even in combination)

irqpoll

noapic, noagp, noapm

nolapic

pci=noacpi

pci=routeirq
