Sorry, my fault. I forgot to tell that I use this image regurarly for 
reading/writing (to host OS environments for the boot clients) without 
any noticeable errors, except the above lines in the syslog. So it seems 
that the writes are OK, at least for the purpose of booting/running 
about 50 machines from this image with various OS-es (even Linux).
