pci ... address space collision: conflicts with ACPI PM1a_EVT_BLK

[WIll Salmon]

On booting the latest Ubuntu Trusty kernel linux-image-3.13.0-58-generic (#97~precise1-Ubuntu) - I'm running Ubuntu 12.04.5 - I get this error in /var/log/kern.log (& syslog) :

pci 0000:00:07.3: address space collision: [io 0x1000-0x103f] conflicts with ACPI PM1a_EVT_BLK [??? 0x00001000-0x00001003 flags 0x80000000]

Does this matter?
Looks like it COULD cause trouble. Would it ?
To be on the safe side I've gone back to 3.13.0-57 ( #95~precise1-Ubuntu )

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1478539

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

I have tried to run sudo apport-collect 1478539 from an ssh terminal (these VMs are headless servers and have no desktop) and a character based window appears where I need to login to Ubuntu One but the field for my e-mail will not let me type into it !

Can you advise what I need to do to get you the info. you need ?

Please note the VM seemed to run OK with kernel 3.13.0-58

I just need advice about the kernel messages (pci 0000:00:07.3: address space collision and what they mean (see below).
I've spotted another message (see below)

They also occur with kernel 3.13.0-59 which has been arrived today.

Thanks

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.2 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Thanks. I'll look into trying this on a test VM and let you know the outcome.

Do I just download these "mainline" kernel files using wget :-
linux-image-4.2.0-*generic*rc4201507271733_i386.deb
and corresponding linux-headers-* ?

and then follow instructions at https://wiki.ubuntu.com/KernelMainlineBuilds to install ?

The affected VMs are headless web servers, running on VMware.

wiki.ubuntu.com/KernelMainlineBuilds says I need to uninstall "select proprietary or out-of-tree modules"

Would this mean I need to uninstall VMware Tools on the chosen VM first ?
It seems to put modules into the kernel with depmod.

Thanks for your help

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
