I just flashed my 5600 with OZ 3.3.5 and first impressions are good, apart from one small fly in the ointment... occasionally the console will pop up a message which will remain on the screen (at the bottom) until a redraw gets rid of it... an example of such messages is:
ts: pxyp=xxx(xxxx/y,xxxx/y)
or
netproto_recv: not up net dev-]flags 1002 (when I put it in the cradle)
they look like kernel messages, but how to switch off?
