--- Comment #13 from Bas Zoetekouw <bas at debian.org> ---
I'm now seeing this issue on my Dell E7470 with kernel 4.15.0 (Ubuntu bionic
18.04).

Exact error (during boot):

After this, the system boots fine, but DRI seems disabled.  E.g., Xorg says:

[    27.868] (II) Module glamoregl: vendor="X.Org Foundation"
[    27.868]    compiled for 1.19.6, module version = 1.0.0
[    27.868]    ABI class: X.Org ANSI C Emulation, version 0.4
[    27.868] (II) glamor: OpenGL accelerated X.org driver based.
[    27.915] (EE) modeset(0): eglGetDisplay() failed
[    27.916] (EE) modeset(0): glamor initialization failed
[...]
[    28.030] (II) AIGLX: Screen 0 is not DRI2 capable
[    28.030] (EE) AIGLX: reverting to software rendering
