@ framiga : I said that from my own experience (there is even a thread here related to my crashes, and I think you were in too). I had several sfs partitions and I update only one of them. After reboot nothing was working anymore until I update the filesystem for all sfs partitions. Anyway I am still with an older version < 1.2 (1.193 IIRC) because some people here said newer versions were slower.
