Beacuse of PTI, I decided to test 4.15-rc6 on most of my test machines. And I happened to notice a radeon problem on RV250 era card with no monitor attached. 4.15-rc1 and earlier kernels did not show these errors, not kernels between rc1 and rc6 have been tested yet. The messages in dmes are strange, like 2 threads trying to poke the card instead of one? Or is it just rrying AGP mode and then PCI mode and this double output is OK?
