By "our driver" do you mean the OFED 1.1 IB kernel drivers (eg ib_sa 
rdma_cm rdma_ucm etc)? I am using this patch series on top of Roland git 
tree of few weeks ago (eg more or less as 2.6.19-rc3) and have not got 
this crash.

By "unload the driver" you mean modprobe -r to which module?

If you know which modprobe -r causes this you might be able isolate the 
problem by doing rmmod to the effected modules one by one from a script, 
  probably the offending one will crash also in this scheme.

Or.
