the new mthca driver and the latest version of IPOIB we constantly receive
errors in IPOIB, and some times it stops working. At least some of the problems
are related to mthca, but we are afraid that not all of them. I'm not writing
the exact locations, as there are more than one. We want to ask you to try

the same problems:</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=913484116-26042006>Here is the
scenario:</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=913484116-26042006>1) Have two machines
connected back to back.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=913484116-26042006>2) run a script that
constantly kills open sm and restarts it every 3 seconds.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=913484116-26042006>for example, use the
script </SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=913484116-26042006>3) run some test
