This bug describes only one example, when I was able to make some logs. My problem is, that command "sync" and may be similar kernel function called from dovecot, mysql, ... stays in "D" state. File cache is not stored on my media. I can read all changed data back from cache, but they are not stored on disks. After reboot all data written to cache is lost.
