Thanks, interesting. In trying to reproduce this, I used a Lenovo S41-35 which has an APU and a dedicated graphics card without a display controller. Normally it attaches radeondrm, with amdgpu it still boots fine. bios0: vendor Lenovo version "BECN55WW" date 07/28/2016 bios0: LENOVO 80JW .. cpu0: AMD A8-7410 APU with AMD Radeon R5 Graphics, 2195.93 MHz, 16-30-01, patch 07030105 .. amdgpu0 at pci0 dev 1 function 0 "ATI Mullins" rev 0x45 .. amdgpu1 at pci1 dev 0 function 0 "ATI Radeon HD 8670M" rev 0x83 .. amdgpu0: MULLINS 2 CU rev 0x01 amdgpu0: 1366x768, 32bpp wsdisplay0 at amdgpu0 mux 1: console (std, vt100 emulation), using wskbd0 wsdisplay0: screen 1-5 added (std, vt100 emulation) amdgpu1: HAINAN 5 CU rev 0x00 I'll look at the code some more and try to find a cause.
