I also have the same problem, sometimes it takes just 1-2 resets to be able to boot, and now i reseted the computer 8 times (2 with full power off) and it finally booted. I think that it fails right before showing the Ubuntu logo and progress bar when switching from console to graphics mode.
My computer is HP Pavilion dm4t-1100 wit ATI 5470HD and Intel. ** Summary changed: - [Radeon HD 5650] Driver crash during recovery boot + [Radeon HD 5650 and 5470] Driver crash during recovery boot and in normal boot -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. https://bugs.launchpad.net/bugs/727620 Title: [Radeon HD 5650 and 5470] Driver crash during recovery boot and in normal boot _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
