           Summary: I/O resource conflict between ACPI and i2c_i801 module
           Product: Other
           Version: 2.5
     KernelVersion: 2.6.28.1
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Modules
        AssignedTo: other_modules at kernel-bugs.osdl.org
        ReportedBy: zmeyski at fastmail.fm


Latest working kernel version: unknown
Earliest failing kernel version: 2.6.28
Distribution: ArchLinux x86_64, self compiled kernel from ftp.kernel.org
Hardware Environment: dell stdio 1537


Problem Description:
dmesg reports I/O resource conflict
i801_smbus 0000:00:1f.3: PCI INT C -> GSI 19 (level, low) -> IRQ 19             
ACPI: I/O resource 0000:00:1f.3 [0x1c00-0x1c1f] conflicts with ACPI region SMBI
[0x1c00-0x1c0f]                  
ACPI: Device needs an ACPI driver

blacklisting the i2c_i801 module gets rid of the message

There is a similar bug report but the eror message is a bit different
http://bugzilla.kernel.org/show_bug.cgi?id=12376

and another one, exactly the same, in red hat bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=470479


Steps to reproduce:
boot, check dmesg
