Any warning about list corruption indicates an initiator side kernel bug.
The OFED 3.12 SRP initiator is based on the Linux kernel 3.12 SRP initiator.
Later SRP initiator versions are much more robust with regard to error
handling. Since OFED 3.18 is not yet available, please consider to switch to
the SRP initiator available from
https://github.com/bvanassche/ib_srp-backport.

Bart.
