[hwloc-devel] hwloc is failing for Pentium D

2010-06-21 Thread Jirka Hladky
Hi guys, I have been always impressed how well hwloc works. Now it seems like I have found a bug on Pentium D, but it might be bug in linux kernel as well. http://en.wikipedia.org/wiki/List_of_Intel_Pentium_D_microprocessors I have reproduced the bug on Pentium D 820 (at Dell's PowerEdge SC430)
