pci boot messages displayed

[Paul Natsuo Kishimoto]

Before the boot splash displays, I see the following messages:

pci 0000:02:00.0: BAR 6: no parent found for of device [0xfffe0000-0xffffffff]
pci 0000:04:00.0: BAR 6: no parent found for of device [0xffff8000-0xffffffff]

I am not experiencing any other bugs which appear to be related to this one, but the messages are an annoyance.

[Jerry Snitselaar (snits)]

The message is in pci_claim_resource() in drivers/pci/setup-res.c. It looks like this has been discussed on linux-kernel:

http://lkml.org/lkml/2009/6/24/373

[Paul Natsuo Kishimoto (khaeru)]

Sorry, Jerry—I had noticed that thread and meant to link it, but forgot.

[Paul Larson (pwlars)]

removed ubuntu-unr tag since this problem is not specific to unr.

[Caroline Ford (secretlondon)]

I get this too on my HP G70 and I think from reading the kernel list thread that its not necessarily a bug.

[spbrereton (simon-brereton)]

Got it reinstalling 9.04 on top of 9.10 development release when updates on Karmic went wrong. MacBook Pro 2.2. I can't boot. Kernel panic - not syncing VFS Unable to mount root fs on unknown-block (0,0)

[John Pettigrew (jrpettigrew)]

Still visible in the new beta. It's quicker to move on past this message than in the alphas, though!

[Frederic (fmorel90)]

I get this message as well on an HP dv5t.

Any way to hide it? It kinda ruins the new boot experience in Karmic by showing up between grub and the Ubuntu logo.

[Anders Sjöström (anders-sjostrom)]

I got this on the new beta on a clean reinstall on my Acer Aspire One 110L. First the message about grub loading. screen clears, then this message reported in the bug above, showing for 1-2 seconds, and then the Ubuntu logo shows up.

[Anders Sjöström (anders-sjostrom)]

Adding tag "ubuntu-boot-experience" as per instruction on http://www.ubuntu.com/testing/karmic/beta

[Anders Sjöström (anders-sjostrom)]

After the latest package upgrades I now have three more lines coming out. (Acer Aspire One 110L, uname -a = Linux netbook 2.6.31-11-generic #38-Ubuntu SMP Fri Oct 2 11:55:55 UTC 2009 i686)

[Paul Natsuo Kishimoto (khaeru)]

As Anders seems to have already noticed, the DRM messages are due to a separate bug :)

[Anders Sjöström (anders-sjostrom)]

Yes, Paul is correct. And faster than me :)

[Micha Moskovic (micha-mosk)]

I also get similar messages:
[ 2.488082] pci 0000:07:00.0: BAR 0: no parent found for of device [0xf0200000-0xf0203fff]
[ 2.488082] pci 0000:07:00.0: BAR 0: can't allocate resource

[ 2.488082] pci 0000:08:00.0: BAR 0: can't allocate resource

and the pci devices in question are my 2 network adapters:
07:00.0 Ethernet controller [0200]: Marvell Technology Group Ltd. 88E8040T PCI-E Fast Ethernet Controller [11ab:4355] (rev 12)
08:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection [8086:4229] (rev 61)

The proposed patch only changes the behaviour for BAR 6 errors, but I get BAR 0 and 2 errors.
I suppose it is nevertheless related, but let me know if I should file another bug report.

[Jack Deslippe (jdeslip)]

Was the kernel patch applied? Can we expect a fix for this issue in a upcoming 2.6.31 kernel update?

[Planeman (planemantheace)]

It got fixed for me in the 2.6.31-13 update.

[Gabe Gorelick (gabegorelick)]

Edited the bug title to reflect the fact that this has nothing to do with Acer hardware.

[Gabe Gorelick (gabegorelick)]

Does anyone still experience this bug with the latest kernel updates in Karmic?

[Filippo Carletti (filippo-carletti)]

After latest updates all messages disappeared.

[Chen Tao (pro711)]

Such messages are no longer displayed after latest kernel updates. Thanks a
lot.

Same here. All okay!

[Bobby Graese (bobby-graese)]

The message no longer shows up on boot, but it still shows up in dmesg:
bobby@rgraese-linux:~$ dmesg | grep "no parent"
[ 1.068488] pci 0000:01:00.0: BAR 6: no parent found for of device [0xfffe0000-0xffffffff]
[ 1.068493] pci 0000:02:00.0: BAR 6: no parent found for of device [0xfffe0000-0xffffffff]

[Gabe Gorelick (gabegorelick)]

These messages in dmesg are just debug messages, and aren't a concern. The only problem was that the messages appeared during boot, which was a priority to clean up for Karmic. Since they no longer appear during boot, this bug can be closed. Feel free to reopen this if anyone experiences this bug again.
