UDEV  [48.317955] change  
/devices/pci0000:00/0000:00:01.1/0000:01:00.0/drm/card0 (drm)

--- Comment #3 from The Linux kernel's regression tracker (Thorsten Leemhuis) (regressions@leemhuis.info) ---
This might be caused by a different or changed kernel config; to check if this
really is a regression you need to verify this on one distro -- and ideally
bisect, too:
