Hi!

It seems we fixed it. :-)  Here a short writeup of what we did:

We originally used 1.4.2 which led to XRC troubles and gave no valuable
error info in dmesg.  When then used 1.4.1 under 2.6.26-2-amd64 and
compiled new modules. This led to error

command 0x13 failed: fw status = 0x1

(amongst others) in dmesg.

After seeing this

http://forums13.itrc.hp.com/service/forums/questionanswer.do?admit=109447627+1255436409428+28353475&threadId=1361415

we  loaded mlx4_core with msi_x=0 and there where no errors whatsoever.
  This also works now with 1.4.2.

Maybe this should be mentioned in the Howtos somewhere, to save someone
else troubles.
