1435 o correctly extends the timeout depending on the size of all
1436 queued messages for both transmit and receive
1437 o will not continue with receive if transmit times out
1438 o ensures that the error callback is done for all queued tx

1441 the callback, and does not overwrite an earlier error
1442 o logic in i2c_probe now correct
1443 - add "vprintf()" function so that "panic()" function can be
1445 - many Hymod board changes
