doing a little bit stress testing, I came across the below oops, when running IPoIB
and couple of iperf/udp sessions, it doesn't look like a problem in the IB stack.
Also with rds, using rds-stress from rds-tools-1.5-1.el5 and "rds-stress -s 192.168.20.18 -p 4000 -t 1
-q 1K -a 1K -D 1M" on the client side, the node running the for-next/IBoE bits and acting as the passive side
of the test, got hanged. Also here, this could be a bug in RDS and not in the IBoE patches, I know that the rds guys queued about a hundred! patches for 2.6.37 so with these patches things might be better. I have the oops trace in jpg, will send to Andy, Roland and Eli. I guess we can continue these tests for 2-3 days and have the push over the weekend, or push it before and get fixes if needed through the -rc cycle.
