[Bug 1443976] Re: splash+KMS+radeon causes screen to freeze

The task "linux (Ubuntu)" has expired because it has had no new comments or updates for more than three years. If this issue is still present in an Ubuntu LTS kernel still under active support, please reopen the bug and provide updated details. If this issue was reported against an Ubuntu kernel no longer under active support but the issue still exists in a currently supported Ubuntu kernel, please open a new bug against that kernel version and provide the updated details, with a reference link to the original bug. This action was performed by an automated process maintained by the Ubuntu Kernel Team. ** Tags added: kernel-autoclosed kernel-autoclosed-expired ** Changed in: linux (Ubuntu) Status: Confirmed => Expired -- You received this bug notification because you are subscribed to linux in Ubuntu.

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: Apr 14 15:01:52 gurren kernel: [ 35.081980] [drm:si_dpm_set_power_state] *ERROR* si_restrict_performance_levels_before_switch failed Apr 14 15:01:59 gurren kernel: [ 42.601562] radeon 0000:01:00.0: Saved 193 dwords of commands on ring 0.
