<br><tt><font size=2>Hi,<br>
This looks very much like bug 793 (https://bugs.openfabrics.org/show_bug.cgi?id=793).
There was a change in the sk_buff definition in 2.6.22+ kernels.
<br>
<br>
Could you verify that the fix posted in the bug is in your sdp_bcopy.c
(or just send me your drivers/infiniband/ulp/sdp/sdp_bcopy.c) file? This
bug got picked up as a patch that gets applied by the build process instead
of a change to base code. Perhaps it is not being picked up for PPC.
I'll check it out.<br>
<br>
Thanks,<br>
JIm<br>

<br>
Hi Jim, <br>
<br>
during the OFED-1.3-beta2 test on ppc64 systems with SLES10-SP1 I saw the
following issue. <br>
<br>
I booted linux kernel 2.6.22 and 2.6.23 on SLES10-SP1 and netpipe sdp fails.
with the following oops: <br>

This issue occurs only on the two kernels mentioned above. <br>
<br>
My Question is , is this the bug you described here: https://bugs.openfabrics.org/show_bug.cgi?id=807
<br>
<br>
or should I open a new one? <br>
<br>
Kind Regards<br>
