Can you provide the output of acpidump please? Also, does this message show up on other kernels, or just 3.3-rc3? Matthew, any ideas? The smbus controller is defined in ACPI space, so may be used by ACPI functions. It's therefore unsafe to let the Linux hardware driver use it. It's an informational warning to let you know why the smbus driver isn't working. (In reply to comment #1) > Can you provide the output of acpidump please?

It's > an informational warning to let you know why the smbus driver isn't working. Just added the acpidump just in case since this warning msg is only present on 3.3 not 3.2. This code got broken somewhere between 2.6.37 and 3.2. It's fixed again for 3.3. The bug persist with kernel 3.6.11-1.fc17.x86_64 My laptop is: HP G6-2145SS. Error message: [ 150.970833] ACPI Warning: 0x0000000000000b00-0x0000000000000b07 SystemIO conflicts with Region \_SB_.PCI0.SMBS.SMB0 1 (20120711/utaddress-251) Same message for me with an Apple Macbook Pro 4,1 booting EFI mode, using kernels 3.6.10, 3.6.11, 3.7.9, 3.8.4, 3.8.5 and 3.9.0-0.rc5.git2.1.fc19.x86_64. (Pretty sure it's all 3.6.x to 3.9.0 inclusive, but those are the ones I just confirmed the warning occurs with.) |
