Created attachment 315517 [details] Use register_netdevice_notifier() instead of register_inetaddr_notifier() This patch was created based on comment 32 in bug #453526 https://bugzilla.redhat.com/show_bug.cgi?id=453526#c32 It applies on top of a 2.6.9-78 kernel. Created attachment 315519 [details] Fix netdev_notify() This patch is based on comment 36 of bug #453526 https://bugzilla.redhat.com/show_bug.cgi?id=453526#c36 It applies on top of a kernel-2.6.9-78 source tree and complements previous attachment #315517 [details] (https://bugzilla.redhat.com/attachment.cgi?id=315517) Created attachment 317446 [details] Fix race condition on interface bring-up Thanks for noticing this, the attachement for comment #1 is not the correct file, this is the correct patch. All three are required to fix the issue. Sorry for the mistake. Thanks Olivier. This is the part of #458934 that we need for RHEL4. Created attachment 318010 [details]
Proposed/posted patch for rhel4.8.
May want to consider backporting to rhel4.7 z-stream if critical need before 4.8 release.
