Created attachment 111633 [details] lspci -vvv of same machine running 766_FC3
Can now confirm that the same thing happens on a dual Opteron under FC3 kernel 770 under x86_64.
Has done the same up through 2.6.11-1.27_FC3smp. UP kernels don't exhibit this behavior.
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you.
Still occurs on this platform with every FC3 and FC4 kernel to date.
Mass update to all FC4 bugs: An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream kernel (2.6.13.2). As there were ~3500 changes upstream between this and the previous kernel, it's possible your bug has been fixed already. Please retest with this update, and update this bug if necessary. Thanks.
2.6.14-1.1637_FC4 has been released as an update for FC4. Please retest with this update, as a large amount of code has been changed in this release, which may have fixed your problem. Thank you.
This bug has been mass-closed along with other bugs that have been in NEEDINFO state for several months.

If you can reproduce this bug after installing all the current updates, please reopen this bug. If you are not the reporter, you can add a comment requesting it be reopened, and someone will get to it asap. Thank you.
