I noticed this dd timiung out when recommissioning the 3 cubietrucks (picasso, metzinger, gleizes) but looking at the log shows this has been happening on braque too. The current code assumes 65MB/s arriving at a timeout of 153s for the 10G file. On arndale-* the logs indicate that it is achieving 95MB/s and taking 105-107s which results in a warning but not a failure: execution took 105 seconds [**>153.846153846154/2**] In experiments on a local cubietruck I observed it achieving a much lower throughput of 40MB/s, which seems to be consistent with what others are seeing: https://groups.google.com/forum/#!category-topic/cubieboard/troubleshooting/7R4HlCDNCTU Therefore calculate the timeout assuming a throughput of 20MB/s, in practice for a 10GB file this will result in a 500s timeout.
