Now i´m botting the kernel, but after the msg 'waiting for udev events' screen goes black.
If i boot it with nomodeset argument it boots in maintenance mode successfully, any clue about this problem?
This is a kernel modeset problem, as you guessed. There is some information in the wiki:
Here are two possible solutions:
1. Use a graphical login manager such as Slim.
2. Or, in the grub menu, add modeset parameters after the kernel line.
I´m using yaboot as loader, i´m on powerpc architecture.
Seems that the problem was solving adding these params to the kernel:
'video=radeonfb radeon.agpmode=-1 noacpi'.
Now i must to figure out how to add those parameters into the yaboot configuration.
Greets and thanks.
