Open bug in LP: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1198453 [ 8.156499] ACPI Warning: 0x0000000000000428-0x000000000000042f SystemIO conflicts with Region \PMIO 1 (20130328/utaddress-251)
hi: This is not a bug and the reason of this log is that driver tries to use system io resource which has used in the ACPI table and the driver normally will not be loaded.
