Message-ID: <201103061335.37050.pluto@agmk.net> (raw)
hi,
i'm trying to setup a basic iscsi example (one target <-> one initiator, described in tutorials)
but the target oopses, probably during 'ietadm --op delete' called from init.d script.
observed on kernel-2.6.37.1(+grsec+vserver) and iscsitarget-1.4.20.2.
# ps aux|grep iet
