This happens with DELL Optiplex 7450 All In One with both an Intel graphics chipset and an AMD Graphic card. I have tested with kernels 4.15.0-29, 4.15.0-64 and latest HWE kernel (5.0.0-29) ; all are affected. As a workaround, it's possible to disabled the radeon card with modprobe.blacklist=radeon kernel parameter. I tried to dump the video bios rom (https://dri.freedesktop.org/wiki/TestingAndDebugging/) without success.
