with 2.6.12 :-/

Software Environment:
GNU bash, version 3.00.16(1)-release (i686-pc-linux-gnu)
KDE/Gnome/E17 - any software environment really

Problem Description:

I have been trying this with various 2.6.13 and 2.6.14
kernels including (archck/ck/kanotix/vanilla etc). 

I start the pcmcia services with /etc/rc.d/pcmcia start, after
which dmesg gives this:

------------------------------------------

---------------------------------------------

Now, if I would insert a memory card (I have only tried this
with SD-cards, as those are the only ones I have at the
moment), I get this:

---------------------------------------------
Probing IDE interface ide2...

-------------------------------------------------

and 'hde:' continues endlessly, sometimes causing a
very noticeable overall slowdown of the entire system.
Rarely, it even causes a kernel crash and a forced cold
reboot.

Steps to reproduce:
1) start pcmcia service
2) insert SD-memory card

(Note: This bugreport was written a while back but I never posted it. Just to
make sure, I tried it with 2.6.15-rc2-mm1 right now and the results were even
worse. After services are started I get a message saying "no pcmcia driver in
/proc/devices", and after card insertion the kernel will oops badly and then crash)
