Description Paul Menzel 2012-08-11 10:38:39 UTC

I am sorry for probably assigning this ticket to the wrong component. It would be great if you could fix that for me.

Testing Linux 3.5 from Debian experimental [1], I noticed that the following warnings are new.

[    7.863922] ACPI Warning: 0x00000860-0x0000087f SystemIO conflicts with Region \PMIO 1 (20120320/utaddress-251)
[    7.863944] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver
[    7.863951] lpc_ich: Resource conflict(s) found affecting iTCO_wdt
[    7.863960] ACPI Warning: 0x00000828-0x0000082f SystemIO conflicts with Region \PMIO 1 (20120320/utaddress-251)
[    7.863976] ACPI Warning: 0x00000828-0x0000082f SystemIO conflicts with Region \_SB_.PCI0.SBRG.PMS0 2 (20120320/utaddress-251)
[    7.863992] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver
[    7.864027] ACPI Warning: 0x00000480-0x000004bf SystemIO conflicts with Region \_SB_.PCI0.SBRG.GPBX 1 (20120320/utaddress-251)
[    7.864044] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver

I do not see these warning with Linux 3.2.23 in Debian Sid/unstable [2].

The system in an ASUS Eee PC 701 4G [3].
