Ok using all the debugs option on a new kernel I achieve to get this
during the problem. I think it is a non sense but...
BUG: soft lockup detected on CPU#1!

Call Trace:

And I achieve to recover my system killing X. Perhaps an interruption
problem. Using full debug the hang disapear strange isn't (smell like
a race condition).
