Aicard 860 serial uart problem in 2.6.16.13-4-smp

[RamaRao]

Hi,

Still seeking help to resolve problem.

Is it a possible IRQ conflict, with both the Ricoh CardBus Controller 
and serial port (ttyS1) being assigned IRQ 201?
Also to be noted is the null ISA  IRQ mask for the cardbus bridge (Yenta 
socket) as shown in dmesg output.

# dmesg
ACPI: PCI Interrupt 0000:05:00.0[A] -> GSI 21 (level, low) -> IRQ 201
Yenta: CardBus bridge found at 0000:05:00.0 [0000:0000]
Linux agpgart interface v0.101 (c) Dave Jones
agpgart: Detected an Intel 915G Chipset.
agpgart: Detected 7932K stolen memory.
USB Universal Host Controller Interface driver v2.3
agpgart: AGP aperture is 256M @ 0x20000000
Yenta: ISA IRQ mask 0x0000, PCI irq 201
Socket status: 30000006

# setserial -av /dev/ttyS1
/dev/ttyS1, Line 1, UART: unknown, Port: 0x02f8, IRQ: 201
       Baud_base: 115200, close_delay: 50, divisor: 0
       closing_wait: 3000
       Flags: spd_normal skip_test

I've tried  updating /etc/pcmcia/config.opts with  "exclude irq 201" and 
the problem persists.

Thanks,
RamaRao
