[Xen-users] modem on serial port in Dom0

[Holger Schultheiß <hoschult@xxxxxx>]

Hi all,

I'm using Xen (stable tarball 3.0.2). I want to connect a modem to my serial
port (ttyS0). After setting "xencons=off" in the module line of my grub, Xen
doesn't use this port itself (dmesg said nothing about ttyS0).

So I did a "modprobe parport" and a "modprobe 8250" says:
FATAL: Error inserting 8250
(/lib/modules/2.6.16-xen/kernel/drivers/serial/8250.ko): Unknown symbol in
module, or unknown parameter (see dmesg)

dmesg:
8250: Unknown symbol uart_get_baud_rate
8250: Unknown symbol uart_resume_port
8250: Unknown symbol uart_register_driver
8250: Unknown symbol uart_suspend_port
8250: Unknown symbol uart_remove_one_port
8250: Unknown symbol uart_update_timeout
8250: Unknown symbol uart_unregister_driver
8250: Unknown symbol uart_get_divisor
8250: Unknown symbol uart_match_port
8250: Unknown symbol uart_add_one_port
8250: Unknown symbol uart_write_wakeup

Did anyone have experience in this error / what went wrong?
Do I have to compile my own Xen0 kernel with serial port support?

Thanks for your help,
Holger
