Re: PC/104 PCMCIA configuration problem

Ralf, 

Those are some strange message re PCMCIA startup, I have never seen 
anything like that. I looked at my /var/log/messages, and it seems 
that we are using the exact same PCMCIA chipset! (Vadem VG-469). I 
have included my system messages below. Notice that while scanning 
IRQs, the kernel detects a status change on IRQ 14. It then assigns 
this IRQ to the i82365 device. My /proc/interrupts includes this:

 14:          4          XT-PIC  i82365

I'm not sure what is going on with yours. Obviously cardmgr is not happy 
with memory probing. But it's strange that no IRQ was assigned in the 
earlier stages. I noticed that your kernel options include [pnp] (plug 
and play) while mine does not. I also noticed that my host options list 
[ext mode] and [isa buf] while yours says none. It might be helpful to 
disable some other devices in BIOS to try to reduce potential conflicts.
It might also be interesting to run pnpdump and see what it spits out
since yours seems to be enabled. My successful system messages for the 
same chipset are below. This is Redhat 6.2 kernel 2.2.14 pcmcia-cs-3.1.8
