I also found a such message here: http://ozlabs.org/pipermail/linuxppc-embedded/2000-May/001402.html
it says:
"... The 8250/16550 driver (serial.c) probes at init-time which will cause
problems. .... "
I want to know are there anyone fixed this problem?
Thanks all.
Best regards,

Dear all,
Hi again, I have asked a same question here before (http://ozlabs.org/pipermail/linuxppc-embedded/2006-January/021617.html), now I have some discoveries ... but I still do not know how to solve.
(My system is a MPC860 Processor Card, plus a custom made PCB to provide a PCMCIA interface, now the latest progress is I can use PCMCIA WLAN cards in this system without any problem. But my main target is use a PCMCIA Bluetooth card ... )
I have noticed when I load up the "serial.o", function "rs_init" must be executed, inside this function call, a function "autoconfig" will be called.
My problem is due to this "autoconfig", it will try to parse a standard uart to determine what is its model. But my case is my standard uart is a PCMCIA Bluetooth Card.
I can simply comment out the function "rs_init" to let the "serial.o" do not run this function. But later when I load the module "serial_cs", many problems happened. (seems "rs_init" will initialize other things that I have not done ...)
Since "serial_cs" (the pcmcia uart driver) needs two function calls in "serial.o" (they are: resgister_serial() and unregister_serial() ), so I really need load up "serial.o" before I can load up "serial_cs.o"
So my problem is, how can I setup such driver in MPC860 environment with a PCMCIA ?
Thanks all~
Best regards,
Chung
