is there anything unusual there?

so, to find out what is wrong the next step would be to recompile
with debug symbols and single step through the failing function?
what should i watch out for?

this is in a self-contained user-mode-linux machine. i could put
it online and people with more clue about the internals and
interest in linux could investigate this. sam, who helped me a
lot untill now, is gone over the holidays.

in fact i put it on
http://developers.skolelinux.no/~andreas/afs-uml.tar.gz

here i start it with 
/usr/bin/linux mem=256M con0=fd:0,fd:1
