--- Comment #27 from John Doe (anode.dev at gmail.com) ---
My RX550 is successfully booted up with 4.20 kernels and newer, but my OS
freezes every minute for 30 secs if I open youtube or play game, and anything
doesn't work upon freeze - I couldn't move mouse or press REISUB. Entire system
is stuck. I downgraded kernel to 4.14 - and it works like a charm without
lags/freezes/stucks. And it seems 4.14 doesn't have AMD DC (amdgpu.dc=0 doesn't
work for me)
