Hello Vu,
 
I am trying to integrate MPP and OFED 1.1 rc3 srp.  
 
Status on following 2 issues.

*	New Host number allocation for controller offline / online - MPP
will handle this with out the need to run hot_add. we need to use
srp_daemon. 
*	scsi error handler invocation - we need to figure out how to
cleanly exit out of error handler after cleaning up all the IO's - THIS
IS THE BIGGEST ISSUE NOW.

 
Panic
 
 I noticed the following panic when I performed sysreboot on controller
A while IO is going on :
 
ib_srp: SRP reset_host called
ib_srp: QP event 1
ib_srp: QP event 1
ib_srp: connection closed
Unable to handle kernel NULL pointer dereference at 0000000000000000
