Yes, thanks, turning off nops helped with some of the timeouts. The mkfs succeeded (very slowly), with this block of errors repeating in the log (see below). I should mention that this is on a asynchronous link, (100mbps initiator <-> 1000mbps target). The initiator is running Fedora 8, 2.6.25.6-27.fc8, open-iscsi 2.0-865. Target is Wasabi Storage Builder. Any ideas?
