Description Vince C. 2005-12-11 06:11:30 UTC
Most recent kernel where this bug did not occur: 2.6.12.xx
Distribution: Gentoo Linux
Hardware Environment: Dell Inspiron 6000 (i915GM, 512 MB RAM, 60GB SATA HD)
Software Environment: 

Problem Description:
PCI Boot error message "Failed to allocate IO resource #7:1000@10000"
Checking dmesg also shows there are bogus resources:
PCI: Ignore bogus resource 6 [0:0] of 0000:00:02.0
PCI: Failed to allocate I/O resource #7:1000@10000 for 0000:00:1e.0

$ lspci | egrep '00:02.0|00:1e.0'
00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML
Express Graphics Controller (rev 03)
00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev d3)
Steps to reproduce:
1. Boot with recent kernels

Actual Results:  
PCI resource Error message but the system continues to boot normally. No crash
occurs.

Expected Results:  
No error message

More information:
I have a Dell Inspiron 6000 and other users also reported that message with
kernels >2.6.13. I have tried workarouds for HP (i.e. patching
drivers/acpi/scan.c as of https://bugzilla.novell.com/show_bug.cgi?id=116763)
but that didn't work.

On my Dell machine, the resource IO error messages are about the PCI bridge and
the graphics adapter, i915GM. I didn't try kernel argument pci=noacpi.

I tried Ubuntu Dapper Flight 2 ( https://wiki.ubuntu.com/DapperFlight2 ) and it
exhibits the same behaviour - it's also based on 2.6.15 series.
Comment 2 Greg Kroah-Hartman 2006-01-04 14:40:42 UTC
The message can be safely ignored.
Comment 3 Vince C. 2006-01-04 14:50:31 UTC
If the error message can be safely ignored, isn't it some way to have it
disappear - by tuning kernel config for instance? I'm just curious about what
triggered it; is it due to a BIOS bug? Does it have something to do with the
DSDT for instance?

Anyway thanks for having taken your time to investigate.
