I have reported that acpi=off solved the problem after trying logging in/out 10 times, all of them with success. However, today a did more tests and even with acpi=off the system frozen, like reported by Pedro Sanchez.

Additional information:
- it is not possible to use ssh to log in from other machine, even ping does not respond. I had a similar problem in other machine but it was possible to log in. In that case, compiz was using 100% of CPU and I found a bug related to it at launchpad. In the current issue, I removed compiz to avoid more problems.
- I tried all options cited in "DebuggingACPI", like acpi=ht, noapic, pnpacpi=off, pci=noirq, nolapic ... freezing as well.

I am attaching all files requested by Jean-Baptiste Lallement, in the hope they help us to find the solution. Any other debug action, please let me know.

BTW:
What I need to do for using vesa driver ?
dpkg-reconfigure does not give me this option, it finishes after keyboard configuration.
