I'm sorry, but I don't know what the problem is. Like I said, I've run
devices on both ports previously without problems, and I've never seen
the situation you're describing. (Disabling port 1 was not suggested as
a solution, only as a way to narrow down the number of possibilities for
what was happening.)
That said, does the ksymoops output look any different now (after the
CONFIG_ETRAX_DEF_R_BUS_CONFIG) change? Are they consistent between
runs, or do they appear to be random?
