Hello, If you are still having the problem try to boot the kernel without the console connected but with a jumper connecting UART0_RX to DGND on the console port (that's pins 1 and 4 on the 6-pin console connector, if you have one).
If you leave the console uart receive pin (or any of the other uarts, I think) unconnected and unterminated it will pick up noise, and the stream of noise will find bugs in the kernel terminal driver and cause crashes. Revision A5A of the BBB board got a 100k pull-down resistor attached to the UART0_RX pin to prevent the noise (I assume), if your board hasn't got a similar pull-down or pull-up you can have the difficulty you see. In fact, even if your clone board includes the 100k resistor like a real BBB you may have problems with this. I have two revision A5C BBB boards which also cause kernel crashes in the serial driver when no console cable is attached, though I have a handful of other boards which run reliably that way, so I think the 100k value is marginal at fixing this on a real BBB. Decreasing the resistance fixes these. Even if your clone board includes the 100k pull-down the differences in board layout or construction may make the 100k value less effective than on a real BBB (where it seems to just barely work) so you may need to use a smaller value.
