Interesting... I actually developed it on a PowerBook G4 with an M10 ! Maybe not the same revision though or maybe not the same fonts. I'll have to dig a bit, I'm not sure I'll be able to do a proper fix in time for the current -rc's so we might have to back the patch off. We'll see what I can come up with this week, I want to try reproducing here and experimenting if doing that alignment & clipping helps. > 0000:00:10.0 VGA compatible controller [0300]: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10] [1002:4e50] > > Here are the fonts I'm using: > > http://ondioline.org/~paul/consolefonts/ > Thanks. One thing you may want to try .. it will result in crap results on screen but would help telling us if that's the cause, is to hack radeonfb to round the image size to a multiple of 32 and see if that stops the lockup.
