Solution:
Disable special CPU/motherboard/IO services. I mean: append kernel parameters with this:
acpi = off noapic nolapic
This can be done before booting, but it's the best to create a new, "safe system start" entry in your grub menu (read manual to do this).

For me this always solved the problem, but it was never a complete solution, because other new problems occured:
1. No more wireless LAN support;
2. Ubuntu is no longer able to turn computer off when trying to;
3. USB devices working slower, especially when connecting USB 2.0 device on USB 1.0 port; this means an exponential-slowing-down.

I haven't test it with wired LAN, but it may be affected too. If you can
live with these limitations then your system will be atomic-secure and
stable, but your system will feel like an old 3.86/4.86 PC in the 90's.

I wonder when this bug will be fixed finally, because I might have given
enough informations about the source of the problem in the beginning of
this comment (IO/APIC).
