that said, i've done some testings (yes, i really have time-> holidays!)
to find out the amount of files triggering the corruptions. started with 
10, 20, 200 (text)files gave me _no_ corruptions. i was already about 
doubting myself, that i copied again my /lib to the fresh fs:

lila:~# mount -o loop test.img /mnt/bench/
lila:~# /bin/cp -a /lib/ /mnt/bench/
lila:~# find /lib/ | wc -l
     475
lila:~# diff -r /lib/ /mnt/bench/lib/ | wc -l
diff: /lib/modules/2.5.65/build: No such file or directory
diff: /mnt/bench/lib/modules/2.5.65/build: No such file or directory
diff: /lib/modules/2.5.69/build: No such file or directory
diff: /mnt/bench/lib/modules/2.5.69/build: No such file or directory
diff: /lib/modules/2.5.70/build: No such file or directory
diff: /mnt/bench/lib/modules/2.5.70/build: No such file or directory
     168
lila:~#

(the warnings are ok, these are correct dead links.)

so, it's 168 out of 475--> 35%. but i still don't know the exact amount 
of file needed to get a corruption. (even with 200 files i should get 70 
corruptions...)

if that would be important/helpful i could do further tests...

Christian.
