first problem I have encountered. Repositioning my screen using OSD position was jumping about all over the place. Finally got it to behave itself. Strange bug
-49- is when your box locks up on booting and freezes on -49-. It's usually a pain to find the culprit as it doesn't produce a crash report.
It was my own fault. I was just preparing to make a fresh backup so I was just deleting a load of crap off my box. It's quicker just to reflash than dig out what caused it.
