Option "Tiling" "false" in /etc/X11/xorg.conf is accepted, but it does not help:

[  1821.661] (==) intel(0): Depth 24, (--) framebuffer bpp 32
[  1821.662] (==) intel(0): RGB weight 888

[  1821.662] (**) intel(0): Framebuffer tiled

[  1913.819] [mi] EQ overflowing. The server is probably stuck in an infinite loop.
