[openib-general] Problems with dsp

[Ely Levy]

I'm trying to run iperf with sdp using svn from few days ago It works find
until the speed goes above 1.49GB (by making block size bigger or running
2 iperf)
Then I'm starting to get weird debug messages in the log and as wall from
root.
Any idea what might cause it?
This is what I see in /var/log/message:
