Hi Daniel,
I think for a substantial improvement here in robustness what you really want is
- kmscon in userspace
- disable FB layer
- ideally also disable console/vt layer in the kernel
- have a minimal emergency/boot-up log thing in drm, patches for that floated around a few times
I assume you refer to this work by David Herrmann: "[RFC] drm: add kernel-log renderer" https://lists.freedesktop.org/archives/dri-devel/2014-March/055136.html
There's also this:
[PATCH v2 0/3] drm: Add panic handling https://lore.kernel.org/dri-devel/20190311174218.51899-1-noralf@tronnes.org/
