Thank you for explanation. While bisect fsck.log was for me like: i have broken
files WTF fsck do not telling me anything. If you mean with "files system
corruption": corrupted orphan, unattached inode, block bitmap difference...;
yes this test clearly reproduce it. But only with md5sum i kan see how big are
real damages.

Here is the script i do:
make modules_install
echo "1v3 done"
sleep 5m 
make modules_install
echo "2v3 done"
sleep 5m
make modules_install
echo "3v3 done do checksum"

mount /dev/sda13 /mnt
md5deep -r /lib/modules/$k_version/* > /mnt/md5sums
umount /mnt

sleep 1m
echo c > /proc/sysrq-trigger
