There is good reason. Our production servers will be linked by fibre. On error, like physical damage to a fibre or terminator, these have a habit of jumping down the Ethernet protocol a couple of stops. So a 1000baseF might become a 10baseF. The upshot is that I need to test with this sync rate set much higher than my NIC's. I have now given this a value 1/10 of the ability of the NIC. But this has not helped. Under protocol B they still jump to 'stalled' when I write data under a resync operation. Ben >> I have included the output from 'hwinfo' if this is any help... > > no. If there is anything else I can check, let me know. I'll even attempt a patch if you have any ideas. Ben
