ok, now the situation is less lethal, but still no proper ide-cs working. 
there are no unknown symbols now, but the other output in dmesg is the 
same. especially, the loop to output "hde: hde1" is here, but if i remove 
the card, it stops and the system is still responsible. 

i checked something i forgot to check before... is the hde device seen 
in /sys somewhere, when the card is plugged in. the answer is yes!:

/sys/block/hde/hde1/

presents itself fully normal like other ide drives. in 
/sys/block/hde/hde1/sample.sh 
i found "mknod /dev/hde1 b 33 1" and tried to run it. successfully!
the result is: in dmesg, the "hde: hde1" output loop stopped and my card 
is working again!!! 

so the trouble seems not only (or not at all) related to the kernel but 
(also) to udev (i use 071), hotplug (mine is 2004_09_23), pcmciautils 
(010) or something else.

can somebody tell me, what state of this process (discovering device, 
loading needed modules, udev creating node under /dev) is the output 
"hde: hde1" to dmesg and how can it be possible that it loops? 

it seems that this chain of processing is stuck somewhere and needs a 
execution of the command to create the node under /dev by hand to finish.

please anybody around with more experience with this systems help or 
suggest where to search.

thank you in advance + greetings,
Damir
