Subject: [2.6] serial port broken?

Hi,

I have a serial mouse, that works ok with 2.4, but in 2.6.0-test[12]
don't work.

The kernel does not recognize the serial port.

root@djgera:~# cat /dev/ttyS0
cat: /dev/ttyS0: No such device

I am sure that the configuration options that use are well, considering
like main to these:

CONFIG_INPUT_MOUSEDEV=y
CONFIG_INPUT_MOUSE=y
CONFIG_MOUSE_SERIAL=y
CONFIG_SERIO=y
CONFIG_SERIO_I8042=y
CONFIG_SERIO_SERPORT=y
CONFIG_INPUT_KEYBOARD=y
CONFIG_KEYBOARD_ATKBD=y
CONFIG_INPUT_MISC=y
CONFIG_INPUT_PCSPKR=y

Apparently kernel recognizes both serial ports, look this
in this port i have connected mouse. ttyS0

no mouse information here.
what is wrong?

Oh! also activate DEBUG in drivers/input/serio/i8042.c and no debug
messages appears when moving mouse.


Thanks in Advance.

attached the dmesg and config.

sorry! i don'n have the option CONFIG_SERIAL_8250, now works perfectly.
the dmesg:

Serial: 8250/16550 driver $Revision: 1.90 $ IRQ sharing disabled
ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A

Sorry! and sorry!
