I can confirm that with linux-image-extra-3.9.0-030900rc5-generic and linux-image-3.9.0-030900rc5-generic the system s not freezing.
As per your request I am going to run apport-collect 1164145. Please let me know if you need anything else from me, and change status accordingly thanks Franco ** Description changed: After upgrading to Linux 3.2.0-39 System always hangs and freezes after the log in. The problem occurs with Linux 3.2.0-39-generic-pae and Linux 3.2.0-39-generic. When system freezes I can still use my wireless keyboard and mouse but any action is not allowed or at least is not displayed. I managed to reboot using the keyboard. When system boot from linux 3.2.0-38-generic the problem does not occur, however with such linux version sometimes a system error is reported and another window is opened warning that 'precise' is no longer supported. Following are some of the info that system automatically collect and send out. Not sure if the two issues are correlated or are the same.
