This bug APPEARS to have been fixed in the latest Ubuntu trusty kernel Linux version 3.13.0-63-generic
So instead of the error: pci 0000:00:07.3: address space collision: [io 0x1000-0x103f] conflicts with ACPI PM1a_EVT_BLK we now get this message : pci 0000:00:07.3: quirk: [io 0x1000-0x103f] claimed by PIIX4 ACPI pci 0000:00:07.3: quirk: [io 0x1040-0x104f] claimed by PIIX4 SMB Could someone please confirm what the original "address space collision" message meant and that the latest kernel HAS fixed it Thanks for your help Will -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1478539 Title: pci ... address space collision: conflicts with ACPI PM1a_EVT_BLK To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1478539/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
