Hello Konstantin,

I have tried to reproduce this but without success so far. Whether I 
install upstream kernel v4.2-rc6 or another kernel version + 
ib_srp-backport on the initiator system, the result is the same when I 
block SRP login on the target system: the ib_srp driver keeps trying to 
log in without creating new SCSI hosts. Are you using a kernel from Greg 
KH's stable repository or another kernel ? And to which values were the 
ib_srp kernel module parameters set (cat /etc/modprobe.d/ib_srp.conf) ?
