Same problem occurs on HP Pavillion, AMD X2, with nvidia. Holding ctrl gets the laptop to boot, and acpi=off will also work (however then halt fails).
I attached my system log files. ** Attachment added: "System log files on failed boot" http://launchpadlibrarian.net/18798474/systemlogs.tgz -- [intrepid] 2.6.27-7-generic almost fails to boot if ACPI module "ac" is not loaded https://bugs.launchpad.net/bugs/282363 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
