Failed to allocate mem resource #6 ...

[Duncan Lithgow]

Every time I boot my laptop, an HP Pavilion dv8220ea (https://wiki.ubuntu.com/LaptopTestingTeam/HP_Pavilion_DV8220EA) I get the text below which I've taken from /var/log/syslog:

[ 0.372370] PCI: Cannot allocate resource region 7 of bridge 0000:00:1c.0

I'm not quite sure what it means but I thought someone should know about it. I haven't seen any problems with the boot up otherwise, runs nicely.

I see someone has said this effects xserver-xorg-video-ati (Ubuntu), maybe it does but I've got an nVidia card. No ATI stuff here.

[Stevn Bartley (sbartley)]

We are getting the same type of error on boot up of a Dapper installed system.

System is using a Supermicro PDSBE-0 board. System installed without error. During system boot we get the following information displayed to the screen:

Uncompressing Linux... Ok, booting the kernel.
[17179574.208000] PCI: BIOS BUG #81[49435024] found
[17179574.208000] PCI: Cannot allocate resource region 7 of bridge 0000:00:1c.0

[17179574.212000] PCI: Failed to allocate mem resource #6:20000@d0000000 for 0000:01:00.0

The system continues past this and boots normally. All seems to be working correctly but this error during boot is an issue we do not want to put in front of our end users of possible.

Thanks.

The same bug around the net:
* http://lkml.org/lkml/2006/8/27/51
* http://lists.infradead.org/pipermail/linux-pcmcia/2005-September/002708.html with linux-2.6.14-rc2 and Novatel-U530 wireless-modem PCcard
* http://ubuntuforums.org/showthread.php?t=243453

Is this bug the same as #56376 ?

[Duncan Lithgow (duncan-lithgow)]

Still present in Feisty Herd 4.

[Ben Collins (ben-collins)]

I doubt these are actually causing problems. These messages started appearing because of some new sanity checks. They'll still be in dmesg, but they wont clutter your screen. I'd seriously check into a BIOS update though.

[Andrew (adhenry)]

I get the exact same error (cannot allocate resource region 7 & 8) on both a 1.5 yr old Acer Aspire 5021WLMi and a brand new HP DV9297ea. I do not think I have the latest BIOS update for the HP--there is an F.15 version and I have F.14--and I have never upgraded the Acer BIOS, but the HP was manufactured in feb 2007, so why would a BIOS update help? Is there any more specific info you can give Ben, that leads you to recommend a BIOS update?

[Duncan Lithgow (duncan-lithgow)]

[Duncan Lithgow (duncan-lithgow)]

I just came across part of this bug in bug #78257 where someone is having trouble with sound in kernel 2.6.20-5. I'm now running 2.6.20-11

[ 0.161771] PCI: Failed to allocate mem resource #6:20000@c0000000 for 0000:01:00.0

I've gone through all the bugs for this kernel which have a similar problem with allocation and given them the tag 'allocate' - I hope that helps with debugging for someone.

[Duncan Lithgow (duncan-lithgow)]

Ben, you've marked this as 'Fix Released'. I'm running the latest kernel (2.6.20-12-generic) and can't see any difference - has this fix been put into the Ubuntu packaged kernel?

[Michael (m-gruys)]

Has nothing to do with BIOS version in my opinion.
I have an Intel DQ965GF with the newest BIOS date smbios.bios.release_date = '02/25/2007'
smbios.bios.version = 'CO96510J.86A.5840.2007.0225.2142'
and I got still a PCI: Failed to allocate mem resource #6:20000@e0000000 for 0000:0
1:00.0 message at booting.
However the system works perfectly. The message is only showed when booting and is recorded in /var/log/dmesg
I hope it is not harmful...

[joeamined (joeamined)]

I have the same problem with a HP Pavilion dv6000.
There was no problem with edgy, but since i moved to Feisty i have got this :

[ 0.206515] PCI: Failed to allocate mem resource #6:20000@d0000000 for 0000:01:00.0

using kernel 2.6.20-13-generic

[Oskar NRK (oskarnrk)]

Same as joeamined, HP Pavillion dv6000, moving from Edgy to Feisty, and I have this error, but after this all works fine.

I can remember that when I use an old Toshiba Satellite A20 and I moved from Dapper to Edgy I had the same (or very very very similar) error.

[m4him (register-lomadeluz)]

I have the same problem on an Asus Z71V. I am at the current Bios. Mine hangs on the error mentioned above and does not boot.
I also have the same error with Region 7, Region 8, and Region 9

[Joon Guillen (flyderman)]

i would like to report the same on my dv6000t.

[Duncan Lithgow (duncan-lithgow)]

Changed back to 'Confirmed' clearly this is not fixed as several people (me at least) are still reporting this problem with the current kernel.

[Frank@Home (kinscherff)]

I have to report same issue on a Laptop MD98000 w/ kernel 2.6.20-15-generic.

I did an upgrade from edgy to feisty. This issue started with feisty. System seems to run without problems, but I have not tested 3D on nVidia Corporation GeForce Go 7400 yet.

Attached find my dmesg output with error message showing up during boot.

It seems that the kernels folks have the problem in their bugzilla:

Does the Ubuntu kernel wranglers automatically notify the kernel folks or should someone else post to the kernel bugzilla?

I checked the posted link above to kernel team bug - it deals with something else (PCI bridge problem)

[Michel Brabants (michel-brabants)]

Hello,

I also experience this bug. Unlike others it blocks me from loading the rt2x00-driver (which causes the error). I am using kernel 2.6.22.9 for x86-64 (Archlinux, so almost vanilla).

Here is the error-message:

PCI: Unable to reserve mem region #1:8000@febf8000 for device 0000:03:00.0
rt2x00pci -> rt2x00pci_probe: Error - PCI request regions failed.
rt61pci: probe of 0000:03:00.0 failed with error -16

The pci-region which it seems to affect (cat /proc/iomem):
feb00000-febfffff : PCI Bus #03
  febf7400-febf74ff : 0000:03:03.0
    febf7400-febf74ff : r8169
  febf7800-febf7fff : 0000:03:02.0
    febf7800-febf7fff : ohci1394
  febf8000-febfffff : 0000:03:00.0
    febff000-febff7ff : pnp 00:0a

The only thing that takes up the memory-region is pnp, which shouldn't blocks other drivers I suppose? Well, I have to say that the loading of this module worked before (quite some time ago). I also upgraded my bios in the meantime. I updated it to the latest version during the weekend (1.7) and the problem remains. My motherboard is the MSI K9A Platinum. I have a radeon (r300)-graphics-card (pci-express) btw. My only problem with my hardware is that the rt2x00 (pci-card) doesn't load because of this error.

I notice this has been marked 'fix released' by the kernel team. Which kernel does that refer to? The current Ubuntu Gutsy kernel or something else?

[Michel Brabants (michel-brabants)]

Hello,

I looked at the kernelbug-conversation, about this and it seems that they just removed the message. Seemingly, the don't think that this is causing any problems.

------- Comment #7 From Andrew Morton 2007-08-02 15:40:09 [reply] -------
Greg, could you please consider removing that message, or rephrasing it
in some manner so that it is less alarming?

  ------- Comment #8 From Greg Kroah-Hartman 2007-10-03 16:03:29 [reply] -------
The message is now gone in 2.6.23. Closing this bug.

Well, I'm not so sure about this, but I'll notice it when I use the next kernel-release.

Greetings,

Michel

I can run X only when I use the vesa driver. When I use the nvidia driver, the screen goes black and i can't do anything but reboot. Booting in to windows vista also gives a black screen, that makes me doubt it's rather a hardware fault.

Hello,

I also still have this problem with kernel 2.6.23.1. Please repoen the bug, it is preventing me from using/testing the rt2x00-wireless driver. A little bit oftopic, but please merge the new wireless stack with the main kernel as soon as possible (including hostapd as soon as possible). Compiling the latest rt2x00 seems not very easy as far as I can read from other (may be wrong).
Anyway, here is the dmesg-output:

[michael perigard (overprescribed)]

I'm receiving the message too, while booting the gutsy alternate install cd, but from the kernel.org bugzilla for this bug:

So I would suggest we close this as "apparently confused BIOS, but Linux
works". ... Greg, could you please consider removing that message, or rephrasing it
in some manner so that it is less alarming? ... The message is now gone in 2.6.23. Closing this bug.

But I'm not sure how to update the status of this bug to reflect this. It's marked as confirmed for two versions of the linux source, but unless someone packports the change into a patch (?), then there wont be a fix on any linux source version before 2.6.23. Maybe mark them as fix released, and the fix is upgrade your kernel to 2.6.23 to remove the message (when it becomes available) or ignore it as a warning...
