Hi
     I plug second keyboard in PS/2 hole and get this:
skipped dmesg

If single pluged in, both keyboards works very fine. If two pluged in,
works only second keyboard with PS/2 connector.
First keyboard has old type connector. inputattach  -ps2ser :  No such
device. Both keyboards detected without ps2serkbd module.


Under ruby I lost my serial mouse. Any programm would use serial hungup my
system.
Sample$ cat /dev/ttyS0
Do not know how to debug this. With printk() I find , uart_open() is caled.
In uart_open()  uart_startup() ever end, uart_block_til_ready() may start,
but never end. If debug is turned on in serial_core.c and serial_8250.c
sometimes I get message:
rs_interrupt_single(4)...
status=f9...IIR=C1...end
Sometimes this message repeated 2...3 times.
