marius 2005-06-04 21:52:56 UTC FreeBSD src repository Modified files: sys/dev/uart uart_bus_ebus.c Log: On AXi and AXmp boards the NS16550 (used to connect keyboard and mouse) share their IRQ lines with the i8042. Any IRQ activity (typically during attach) on the NS16550 used to connect the keyboard when actually the PS/2 keyboard is selected in OFW causes interaction with the OBP i8042 driver resulting in a hang (and vice versa). As RS232 keyboards and mice obviously aren't meant to be used in parallel with PS/2 ones on these boards don't attach to these NS16550 in case the RS232 keyboard isn't selected in order to prevent such hangs.
