Hi Chet,
I regret that some of the latest patches could not be included in the 
final release, but the main issue was that the patches came too late.
Please note:
1. ehca was added to OFED 1.1 in RC3, 31-Aug 
(http://openib.org/pipermail/openfabrics-ewg/2006-August/001234.html)
2. Most user space issues raised by IBM were reported only on RC7, which 
was supposed to be the final RC, with no more major changes.
We nevertheless accepted patches that you submitted at that late phase 
which affected only ehca.  However, the patch in question (on the 
configure file for user space) touches ALL components of the userspace 
build, and was a very large patch as well.  At that late date (2 days 
before final release!), it is impossible to start testing a change of 
this magnitude on ALL platforms to verify that the change was not harmful.

I agree we should learn from this experience: in the future, /please 
/start your testing as early as possible so that problems of this nature 
are caught early in the development cycle, and do not need to be 
addressed at the last possible moment.

I am sure that in the next release things will go more smoothly since 
this was IBM's first participation in an OFED release.
