Red Hat Bugzilla – Bug 474891
PCI Domain support for HP xw9400 and xw9300
Last modified: 2009-02-20 12:44:36 EST
Description of problem:
xw9400 and xw9300 systems blacklisted for PCI Domain support. This was done at a time when PCI Domain support was not enabled in RHEL5 and these systems did not boot because of the extra domain.
Version-Release number of selected component (if applicable): -125.el5
How reproducible: 100%
Steps to Reproduce:
2. lspci -D
Actual results: lspci -D output shows single domain.
Expected results: lspci -D output should show two.
Additional info: Noticed by tcamuso, onsite engineer for HP.

RHEL5 fix for this issue
Prarit tested his PCI domain patch on these systems by removing them from the blacklist.
However, HP feels that we are too close to the end of the 5.3 cycle to make this change and get adequate test exposure before the GA date, so we would like to defer the fix to 5.4.

Output for lspci -D on the -129 kernel
Attached a text file with the output after running lspci -D on the 2.6.18-129 kernel. I do not see a difference in the text file 128kernel.txt when running a diff againest the 129kernel.txt file. Is this expected behavior?

This wasn't committed to a kernel until -130.el5 .

Output for lspci -D on the -130 kernel
I'm assuming this is now fixed since I was able to boot with the -130 kernel with AHCI Bus Segmentation enabled.
Yes, I believe it is fixed and this BZ can be closed.
Updating PM score.
