PCI: Failed to allocate mem resource #6:20000@88000000 for 0000:01:00.0

Bug Description

Hi,
I get this error in dmesg.

I have an Intel 975XBX M/B with a nVidia 7600GS card in it.

I get an error for each of the three VGA cards in the 3 PCIe slots and I am wondering if this is why my multiseat is extremely unstable (hangs after a few minutes, etc).

Could be similar to bug #26521

I have the latest 1334 BIOS on the M/B
I'm using ubuntu dapper and uname -a gives:
Linux gl0 2.6.15-26-686 #1 SMP PREEMPT Mon Jul 17 20:14:14 UTC 2006 i686 GNU/Linux

Thanks,
Zoltan

Hi - Sorry for delay - had to wait until lunchtime before I could boot
the people off the PCs and re-kick them :-)
(I have 4 of these PCs in production, all with the same problems).

Hi Guys,

Any further ideas?
I really need to sort this out.
Is it a linux/boot issue?
Buggy BIOS?

If someone could please give me a clue as to what to swopout or do to try tonarrow down the cause....
Thanks,
Zoltan

Hi Vassili,

Thanks for remembering me and working on the problem.

I'm running 2.6.15-27-686 and it still shows the errors.

Which particular version is this fixed in, and when will it be available
for download/update?
Also, has this anything to do with the fact that I have to use the
pci=nommconf bootstring?

Thanks,
Zoltan.

This bug has had no activity for a considerable period. This is a check to see if there is still interest in investigating this bug report.

Changed in linux-source-2.6.15:

I think this bug is ongoing. So please keep it open! There is A LOT of people having this error message. Please see ubuntu forums: http://ubuntuforums.org/showthread.php?t=415239 - This is just one of the MANY open and apparently unsolved issues.
I am happy to help if proper instructions are given! :) KR, Harald

Here is my error message: [ 19.582353] PCI: Failed to allocate mem resource #6:20000@f0000000 for 0000:01:00.0
I use a Lenovo T61 laptop type 6458-CTO Intel® Core™ 2 Duo processor T8100 (2.1GHz 800MHz 3MBL2), NVIDIA Quadro NVS 140M (128MB), running Ubuntu Gutsy.

Harold,
If you are receiving this (or similar) error message but it appears to be causing no ill effects then this is the bug report you are looking for:
Bug #159241
The several comments I read on the forum you linked to above indicate this is an error message with no ill effects.

It appears from the upstream commentary that it has to do with BIOS resource allocation double-up which has no ill effects but the Linux kernel correctly notes the issue during boot up. While this is not a Linux bug the devs appear to be lowering the error reporting level so that normal users don't see this message. The message will probably not appear in Hardy.

This bug ( Bug #55416 ) hasn't [yet] been marked as a duplicate of Bug #159241 because the original reporter (Zoltan) had a system stability issue with regard to a very specific system configuration. It's not clear yet whether Zoltan's reported error message is related to Zoltan's instability issues or not.

Thanks.

The error message I am having fits your description and does not cause any ill effects whatsoever. Thank you for the comments. KR, Harald

Marking this as a duplicate of Bug #159241 as no other comments have been offered. If anyone thinks this referral is errant then please re-mark this bug to NEW. Thanks.

Hi All/Gareth,
Sorry about the silence on my side....

I still get:
root@gm0:/home/zls# dmesg | grep ailed
[ 33.917095] PCI: Failed to allocate mem resource #6:20000@90000000 for 0000:01:00.0

I have given up worrying about it - but I have to confess it would be nice to know the exact cause, in case it really is causing performance or other hidden problems.

I am running 8 3-seater multiseats that are (by now) pretty stable - and still on ubuntu 6.06 (on all but 1 of the boxes).

So, please don't close this as it really should be explained or sorted out.

Regards to all,
Zoltan

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this linux-source-2.6.15 kernel bug to the new "linux" package. We appreciate your patience and understanding as we make this transition. Also, if you would be interested in testing the upcoming Intrepid Ibex 8.10 release, it is available at http://www.ubuntu.com/testing . Please let us know your results. Thanks!
