More info on this.
I first noticed this when setting up my new install on the 64gb SD card.
I wrote the LE9 image to SD card.
Once loaded up I changed a couple of settings like I normally do (basic stuff like my location etc).
Then I connect my external drive with my media on reboot and check all is mounted correctly.
The drive is formatted in ext4.
When I first added my movies folder to Kodi and scanned everything went fine the was only 86 movies.
But then when I scroll through my list of movies that's when it will completely freeze up the pi.
It did this a couple of times when I first added to library.
It seemed once it had fetched artwork when scrolling through all my movies that the freezes didn't appear again or so I thought until adding more.
I now have 91 movies some added to library no problem some caused the freeze.
For example, tonight I copied over a movie from my computer and update my library (this part always goes ok) then when I navigate through my library to that movie that's when it will freeze my pi up and I have to pull the plug (even left it 10mins to see if it would respond) so it almost seems like when highlighting a newly added video and it tries to fetch artwork that's when it freezes.
Thanks in advance
