Comment 57 for bug 588194

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]

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.
