I experienced similiar problems when notebooks (their CPU) are getting hot:
- the machines stuck / freezes and i wasn't able to do anything.

Machines got hot when the power management didn't work as expected...and the problem was the ACPI or APM configuration/manipulation in BIOS (if there was any possibility at all) or in the kernel...and things got better and started to work with ubuntu 8.04

The great problem is, so do i think, that there are many hardware vendors, and they all have different components from different manufacturers and they all have different BIOS Software and not all have the time to stick to conventions/norms/standards or they don't like the standards....but it is really hard to find out, if it is a real hardware damage or a workaround, with which one could live...

In your case there must be a solution, because it worked with 10.04 LTS, so it has to work with 12.04 LTS too.
Maybe there was a certain/extra kernel module in10.04 in use for your notebook, which made it work as expected?
