I too had major issues with the last release and had to revert back. It was thrashing the disk madly and thus you could not access or stream media from the unit.
if you go back on the forum you’ll see lots of posts.
I don’t often disable automatic updates. I did after that upgrade.
So … before I do this I’m going to enable SSH and ask… how is this one looking and will it not cause the performance problem that the that version caused?
