[ewg] OFED-1.3-beta sdp issue

[Stefan Roscher]

Hi Jim,

during the OFED-1.3-beta2 test on ppc64 systems with SLES10-SP1 I saw the 
following issue.

I booted linux kernel 2.6.22 and 2.6.23 on SLES10-SP1 and netpipe sdp 
fails. with the following oops:

This issue occurs only on the two kernels mentioned above.

My Question is , is this the bug you described here: 
https://bugs.openfabrics.org/show_bug.cgi?id=807

or should I open a new one? 
  
Kind Regards
