Hi Guys,

I am trying to bring pcmcia up on my mpc855 based board. I am using
kernel-2.4.18 and have pcmcia extensions.

I am making pcmcia as module, so  I can insmod pcmcia_core and m8xx_pcmcia
and ds. When I insert the card and start cardmgr, this is what I get.


Starting PCMCIA services: cardmgr[79]: watching 2 sockets
done.

What am I missing here?? why is it trying to insmod char-major-4?? and why
does the kernel panic??

The kernel panics because in 2.4.18 a call to request_irq() would simply
panic.  If you hit google, you can probably find a patch to airo.c to
make it use request_8xxirq() and 'work', or if you update to 2.4.21 (or
was it 2.4.20, I forget now), this is not an issue.

Now that I think of it, all you might have to do is to change the call
in airo.c from request_irq() to request_8xxirq().  But I haven't done
that myself.
