This message interrupt the graphicl boot. Also some times my computer gets froozen during boot and stop respond to keybaord key press and I have to do a hard reset.

[AMD/ATI] Ellesmere [Radeon RX 470/480/570/580] (rev c7) uname -a Linux jarvis 4.14.9-1-default #1 SMP PREEMPT Mon Dec 25 15:42:48 UTC 2017 (9423ca2) x86_64 x86_64 x86_64 GNU/Linux lsb_release -a LSB Version: n/a Distributor ID: openSUSE Description: openSUSE Tumbleweed Release: 20171231 Codename: n/a found below from arch linux wiki: Also, since kernel 4.13, adding the amdgpu.si_support=1 radeon.si_support=0 or amdgpu.cik_support=1 radeon.cik_support=0 kernel parameter is required. Otherwise, AMDGPU will not start and you will end up with either radeon being used instead or the display being frozen during the boot. ref: https://wiki.archlinux.org/index.php/AMDGPU Sounds alot like my issues. -- You are receiving this mail because: You are on the CC list for the bug.
