I have a V13 notebook and the same problem happen using Debian 6.0 (kernel 2.6.32 AMD64) in power on and back to suspend and hibernate. During the boot messages, I see an ACPI error: ACPI: I/O resource 0000:00:1f.3 [0x1c00-0x1c1f] conflicts with ACPI region SMBI [0x1c00-0x1c0f]
A "lspci" show: 00:1f.3 SMBus: Intel Corporation 82801I (IHC9 Family) SMBus Copntroller (rev 03) Other references to 0000:00:1f.3 on dmesg: [ 0.203876] pci 0000:00:1f.3: reg 10 64bit mmio: [0x000000-0x0000ff] [ 0.203899] pci 0000:00:1f.3: reg 20 io port: [0x1c00-0x1c1f] [ 3.688520] i801_smbus 0000:00:1f.3: PCI INT C -> GSI 19 (level, low) -> IRQ 19 [ 3.688529] ACPI: I/O resource 0000:00:1f.3 [0x1c00-0x1c1f] conflicts with ACPI region SMBI [0x1c00-0x1c0f] Since I added "acpi=off" in kernel line (on grub conf), this problems (power off during boot and ACPI error message) was solved. But I can't suspend/hibernate anymore... =/ I'm downloadind natty-alpha1 to test. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/588194 Title: Unexpected power-off during boot or when resuming from suspend -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
