5.0.3 dmesg

xorg crashes when running kernel 4.20.13 and later versions (tested all the way to 5.0.3). Downgrading to 4.20.12 worked.

xorg fails with:

    modeset(0): failed to set mode: Invalid argument

Attached dmesg (drm.debug=14) and xorg logs for 4.20.12 (working), 4.20.13 (first version I noticed the issue) and 5.0.3 (latest version I have on hand, also broken).

Added output for lsmod, lshw
