I am experiencing boot issues with the latest build. I updated from 010 where I did not have any boot issues, or even if there were any, they were not as noticeable as these. It boots once in 5 times maybe. I have to constantly power it off. I thought that it's the CEC, but disabling it did not change anything.
I noticed that powering on the device before I power on the receiver it is connected to does the trick sometimes, but I can not confirm it 100%.
