When I start the system with YWRAP activated I have scrolling 
problems , in fact when I make the screen scrolling for a while (for 
example during the examination of a document with "less" or during the 
compilation of a software) , on the screen starts appear colored lines 
on the screen and these starts scrolling . When the screen is full of 
this lines these disappear and the text is back , but after few scroll 
again these lines appears. With 2.4.21-ac4 kernel the problem is more 
evident than the 2.4.21 "vanilla" .  If I reboot the system doesn't 
appears lines anymore, but instead of the lines appears words of the 
precedent boot of the system, seems like that the video memory have not 
been reset , and that the FB takes parts of the Video data Junk 
remained after the reboot and visualize these on the screen. Seems like 
an error in addressing the video memory .

With 2.4.20 and precedent this doesn't happen .

Please help me :cry:

Bye
