I had this issue some weeks ago on an almost daily basis, then it seemed to have disappeared but as it occured again today I think I have to post it. Usually the box froze just by trying to zap to another channel. Today it happened while I was in the channel list trying to move the cursor to a different channel. Openpli version is from March 1st.

 

Here's the dmesg output:

Hm, but shouldn't then not only this but all other boards about other images as well be full of reports on this issue? Just zapping doesn't seem to be such an odd thing.
