Hi, a month ago i have installed custom kernel from this thread at Polish ubuntu forum: http://ubuntu.pl/forum/viewtopic.php?f=216&t=160361 Months of use, and i have no more crashes and no more rainbow on brightness change. The problem is in generic kernel. The only problem is that the system boot 15 - 25s longer :( But faster than windows :)
