I can confirm the same happens here on an i.MX6q board on current master. I don't know what's happening here. The last thing I see is that fec_tx_task_enable() is entered. Strange enough the same works on i.MX53 whereas on i.MX8M I get "ERROR: eth0: transmission timeout" on the second ifup. This is really strange. It seems fec_tx_task_enable() brings down the whole SoC, but on the other hand the FEC works properly in a chainloaded barebox, which should - from the view of the ethernet controller - be the same as a repeated ifup/ifdown sequence. I have no idea what is going wrong here.
