Description of problem: the xmlbuffer self check fails on ppc, see http://ppc.koji.fedoraproject.org/koji/getfile?taskID=256586&name=build.log The difference between the first exported buffer and the second exported buffer is in the lines <page_type size="17179869184" count="0"/> vs. <page_type size="4294967295" count="0"/> Version-Release number of selected component (if applicable): hwloc-1.2-0.fc16 How reproducible: always Steps to Reproduce: 1. ppc-koji build --scratch dist-f16 hwloc-1.2-0.fc16.src.rpm 2. 3. Actual results: http://ppc.koji.fedoraproject.org/koji/taskinfo?taskID=256555

Looks like we cast the pagesizes to unsigned long during XML import+export. Please try this patch. It should work with your 16Go pages :) Thanks!

Ho, you'll need this too, otherwise the lines would be missordered. I reproduced and fixes the problem on x86_32 so I assume it'll work for you too.

Hi Brice, I have tried to apply your patches https://bugzilla.redhat.com/show_bug.cgi?id=724937#c2 https://bugzilla.redhat.com/show_bug.cgi?id=724937#c3 to both hwloc-1.2 and hwloc-1.2.1 but it's failing: =================================================================== patching file src/topology.c Hunk #1 FAILED at 889. patching file src/topology-xml.c Hunk #1 FAILED at 280. =================================================================== Could you please provide a new complete patch using version hwloc-1.2.1 as base? http://www.open-mpi.org/software/hwloc/v1.2/downloads/hwloc-1.2.1.tar.bz2 Thanks a lot! Jirka
The patch I backported to v1.2 is https://svn.open-mpi.org/trac/hwloc/changeset/3834 By the way, there's a 1.2.2rc1 online, and I will do the final 1.2.2 next week. Brice
Hi Brice, thanks a lot for creating 1.2.2rc1. I have tested it and the issue is fixed:-) I will wait for 1.2.2 to submit a new rpm for Fedora. Thanks Jiri
