--- Comment #120 from lucky_beta lucky_beta@126.com --- I've read the previous comments carefully and I'm using the ati3470 GPU card which is the same as "Sergey", also the problem similar, when trying to boot with "radeon.dmp=1", the screen goes white gradually and just hang there, sometimes it can boot but the windows respond very slowly. I want to know whether the problem has been fixed. I just can't find any sure answers from the comments above.
