perfSONAR User Q&A and Other Discussion

Hi Colin;

Sorry for the late reply on this email, I am CCing the 
'performance-node-users' list on this question since that is a more 
appropriate venue.

The latest release may be a better option since we corrected many 
problems in the last couple of RCs and have moved to the final recently. 
 Would you be able to try that and see if the same problem persists? 
If the driver is not included we can definitely add it as a module. 
Would you happen to know the kmod name offhand?  Also - for testing 
purposes it may be better to start with the new NetInstall version 
instead of the LiveCD.

Unfortunately we will be dropping support of the 3.1.3 series early next 
year.  I think it would be best to stick with 3.2, and hopefully we can 
resolve the problem.
