Red Hat Bugzilla – Bug 506805
non-sequential node numbering on some Nehalem/5500 series multi-socket mainboards causing trouble
Last modified: 2010-06-28 09:08:14 EDT
On certain Intel 5500 / Nehalem multi-socket systems, the node numbering
has become non-sequential in Fedora11.
The problem does not exist in RHEL 5.3.
The issue can be observed like this:
# ls -ld /sys/devices/system/node/node*
drwxr-xr-x 2 root root 0 2009-06-18 09:30 /sys/devices/system/node/node0
drwxr-xr-x 2 root root 0 2009-06-18 09:30 /sys/devices/system/node/node2
It is causing various things that assume sequential numbering to cause
trouble. Examples in BZs 506795, 506590, 499633
It appears there is a community-proposed fix to this problem already.
The mail archive server didn't seem to thread it so check out these

Those patches were acked by yhlu but haven't appeared in the acpi tree, not even in the 'testing' branch...
I applied the patches to 2.6.30-git14 and this issue was fixed on the

Patches are still not upstream.
This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '11'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 11's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 11 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
