** Tags added: regression-update ** Description changed:
Hi, I just performed a > 150 MB upgrade to 3.2.0.27 with my Thinkpad T400 and after reboot Ubuntu stopped working: I do get the grub screen but after choosing "Ubuntu, with Linux 3.2.0-27-generic" a black screen with blinking cursor appears and stays. After that, I can only shutdown the system with the power button. I have a second OS to choose from in grub which is Windows Vista but booting fails as well. - Please, any help is greatly appreciated. (Wished I had not done the last backup a week ago...) - --- + Please, any help is greatly appreciated.
