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 links: http://marc.info/?l=linux-kernel&m=124264032632662&w=2 http://marc.info/?l=linux-kernel&m=124264032932693&w=2 http://marc.info/?l=linux-kernel&m=124264064200735&w=2 http://marc.info/?l=linux-kernel&m=124264064400743&w=2 This problem was observed in Fedora11 with kernel 2.6.29.4-167.fc11.x86_64 We wanted to get this on the Red Hat radar. I'm guessing it is already and that I didn't perhaps use the right search terms to find existing bugs. In that case, if you could kindly duplicate this, I would appreciate it. Thank you.
Created attachment 348720 [details] dmesg output from problem system
confirmed problem present in 2.6.29.5 community kernel.
also confirmed it's still a problem in 2.6.30-git14
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 problem system. I also posted this detail in to the thread in LKML.
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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
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.
