Hi all,

I have run into two bugs on PPC64 on 2.6.32 kernel.

Version:
lt-lstopo 1.0.1

BUG #1: No Socket information in lstopo output:

./lstopo
Machine (3654MB) + L2 #0 (4096KB)
  L1 #0 (64KB) + Core #0
    PU #0 (phys=0)
    PU #1 (phys=1)
  L1 #1 (64KB) + Core #1
    PU #2 (phys=2)
    PU #3 (phys=3)

Fixed in the latest version (tried hwloc-1.1a1r2301.tar.gz)
lt-lstopo 1.1a1
./lstopo
Machine (3654MB) + Socket #0 + L2 #0 (4096KB)
  L1 #0 (64KB) + Core #0
    PU #0 (phys=0)
    PU #1 (phys=1)
  L1 #1 (64KB) + Core #1
    PU #2 (phys=2)
    PU #3 (phys=3)

I have attached /proc/cpuinfo ("bug_1-ppc64-cpuinfo")

BUG #2
On some PPC64, kernel 2.6.32 I have crash when running 
$ lstopo a.txt
Segmentation fault (core dumped)
$ gdb /usr/local/bin/lstopo core.8771
Program terminated with signal 11, Segmentation fault.
#0  0x00000000100060b4 in .merge ()

It appears only on some PPC64 boxes.

This issue is also gone with in the latest version (tried 
hwloc-1.1a1r2301.tar.gz)

I wonder if you are aware of these problems. let me know if you need more 
details.

Thanks
Jirka
