You are correct - the Sun errors are in a version prior to the
insertion of the SM changes. We didn't relabel the version to 1.3.2
until -after- those changes went in, so you have to look for anything
with an r number >= 20839.
The sif errors are all in that group - I would suggest starting there.
I suspect Josh or someone at IU could tell you the compiler. I would
be very surprised if it wasn't gcc, but I don't know what version. I
suspect they could even find a way to run some debugging on for you,
if that would help.
The Cisco errors were caused by some config/fabric problems - Jeff is
physically there today, so hopefully those will get fixed and we'll
see his tests. IIRC, he was seeing these problems before, so hopefully
we can see if they are still present.
