Yes, reverting just 835d844d1 on top of 3.7.0 fixes it. I also see why now. That commit changed the module name from 8250 to 8250_core in the makefile, so clearly 8250.nr_uarts = 16 isn't going to get parsed. Adding 8250_core.nr_uarts = 16 seems to work fine. This wasn't immediately obvious because the whole thing is built-in and not a module. Thankfully, looking in /sys/modules/ still works and that showed up pretty clearly. So I guess this isn't really a break in functionality as much as it's a driver rename. Not sure if it's worth fixing in some form or not. josh -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
