Overview: System doesn't boot on Samsung R460-FSSS without acpi=off or pci=noacpi flags. Steps to Reproduce: Boot with acpi=on Actual Results: The system is rebooting The full bugreport you can found on https://bugs.launchpad.net/ubuntu/+source/linux/+bug/998758 Actually, I'm opening this bug because Joseph Salisbury (from bugs.launchpad.net) asked me to do this. I've no idea, what additional information can help you. But i'd love to deliver it to you.
Please reproduce with the nvidia driver removed from the configuration. Please describe in more detail how the boot fails. Does anything get printed on the screen? (put "debug" on the cmdline) > ProcVersionSignature: Ubuntu 3.2.0-24.37-generic 3.2.14 Can you try an older release to see if this is a regression? pci=noacpi skips the ACPI enumeration of the PCI busses, but otherwise ISTR it doesn't change much else -- maybe something w/ interrupts... Please attach the output from acpidump so we can see what your DSDT does.
