I don't know what causes your problems, but be sure you have a loss-free connection provided by pause point-to-point or thru a DCE switch. Otherwise you'll see lots of retries on writes especially. You might have better luck with a the newer target setup using SCST and fcst, which can work under 2.6.34 or 2.6.35. You can get them via svn co https://scst.svn.sourceforge.net/svnroot/scst/trunk which gets the very latest development version. Then under that look at fcst/README.
