SubjectRe: [i915] BUG: Bad page state in process Xorg
From
Hi,

It turns out that this seems to be a bug in udl DRM driver.

I bisected the problem to this patch:

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/gpu/drm/udl?id=5dc9e1e87229cb786a5bb58ddd0d60fee6eb4641

With kind regards
Thomas
