Whoaa, great. > > No. 0.1.8 lacks a lot of my stuffs I have a small problem with radeonfb in 2.4.22-pre5 (+manually created radeonfb.h file). During boot, when the console is switched over to the frame buffer device, the screen becomes corrupted. Mostly by white squares in a grid pattern and some squares with other colors. Between the squares, normal characters can be seen, but each character is duplicated. Here is a picture: (not very sharp unfortunately) http://w1.894.telia.com/~u89404340/radeonfb.jpg Text added after the switch is not corrupted, so eventually the corruption is scrolled off the screen and after that the framebuffer appears to be working correctly. 2.4.22-pre3 does not have this problem. I haven't found a patch for the vanilla 0.1.8 version, so I don't know if that version also has this problem. I think someone has reported a similar problem in 2.5.x, but I don't remember the details.
