PCMCIA IDE failed on PXA270 board

[Ray Zhao]

HI, there
I met a problem with my pxa270 based board. I am using linux2.6.12.3.
I modified the pcmcia driver i82365 to support my intel spd6722. I
posted this in the ARM Kernel list and got some help from there, but I
did not solve the problem yet. The problem MAY be the interrupt. I
port the driver from 2.4 kernel. There are, of cause, changed on data
structures. I find the fields which 2.4 drivers filled, but I did not
actually filled all new Fields introduced from 2.6 kernel. Is there
some new fields I MUST fill?
I tracked the code, in the cs.c. There is a function named
pcmcia_request_irq() which is called from ide-cs.c. In this function,
I notice I did not use config_pcmcia_probe, and in the
req->attributes, I do not have IRQ_HANDLER_PRESENT. So I did not call
request_irq() at all. Is this the reason I always get a message tells
me "lost a interrupt"?
I used same file system which works with 2.4. Do I need a NEW file
system to make this work?

here is what I got frm console:
