Title:
  splash+KMS+radeon causes screen to freeze

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have Radeon HD 7970 video card and I'm using open source radeon driver.
  If I try to boot with kernel parameters "quiet splash", system boots normally at first, splash screen is shown, but when it's time to start X server, screen instead shows garbage (http://s014.radikal.ru/i327/1504/3a/281b75b0ef2d.jpg), turns off and on several times, then shows quickly changing pattern (http://s020.radikal.ru/i704/1504/88/b9d2169bca29.jpg). The system don't respond to Ctrl-Alt-F?, but I still can connect using ssh. "reboot" doesn't work. kern.log has following error messages:
