OK, I will try... before doing that just one question:
- when I tried to simply copy 2 MB large file from NFS mounted file system to 
the flash file system, it took me from 5 to 20 minutes. It took me 5 minutes 
after rebooting and over 20 minutes after doing it for the fourth time (with 
no rebooting in between). Is 5 minutes normal for writing such a big file to 
flash file system?
