Additionally, I found that I can load the newer scst code if I use the
kernel-supplied modules and the standalone srpt-1.0.0 package that I
think you provide Vu. I was about to try it along with dropping a
module param for ib_srpt (I was using a thread count of 32 that had
given me better performance on an earlier test). I'll report back on
this.
Not much luck using the newer scst code and default kernel modules
(Running CentOS 5.2). If I try using the default kernel modules on the
initiator, I can't get them to see anything (the ofed SM pkg doesn't see
any devices to run on). When using the regular OFED on the initiator, my
target dies when I try to attach to the target on the initiator:

This can happen if the target driver frees some IO or TM command twice,
by, eg, calling scst_tgt_cmd_done() two times for the same command.
