Indeed many i915 Gen4
unfortunately don't have
all the data needed for bisection, as the old kernels have been wiped off
the machine in the meantime.
Is this a known issue?

Three different issues, it seems. Two ring initialization problems,
one went away in 3.16 (for me), second did not (suspend for jikos),
third -- trivial issue with 8to6 dither.
That's correct assesment.
The ring initialization failure I reported is still there.

is or not?
No, but there is a workaround for cases kernel finds out that it cannot
execute GPU commands (because the rings failed to initialize), and instead
it falls back to CPU rendering directly into the framebuffer.
So it's highly sub-optimal, but works around the complete wreckage.

like once in 40 resumes). But it was getting gradually worse
and worse with newer kernels, and with current tree (both Linus' tree and
drm-intel-testing), I am getting it 100% reproducibly on every resume.
This makes bisection completely impossible though.
