I guess that's where things start to go bad. genirq changes? > BUG: warning at drivers/serial/sn_console.c:976/sn_sal_console_write() There's a warning patch in -mm which shouts when someone does a busywait delay of over a millisecond, and sn_sal_console_write() is doing mdelay(150). And it's doing that mdelay because it thinks port->sc_port.lock is already held.
