it...

Graphics card: Radeon R9 390X (Saphhire 11241-04-20G)
Display: LG 31MU97 (via DisplayPort)

With Linux 4.4.x, 4096 x 2160 @ 60 Hz progressive output was working wi=
th
standard CVT timing.

With Linux 4.5.x onwards, standard CVT timing at that resolution fails (no
signal) with the following dmesg output:

kernel: [drm:radeon_dp_link_train [radeon]] *ERROR* channel eq failed
kernel: [drm:radeon_dp_link_train [radeon]] *ERROR* channel eq failed: 5 tr=
ies

CVT-R timing results in output, but with a flickering/corrupted full-height
band down the right hand side (it approximates the intended output, but pix=
els
seem be to be corrupt in single-pixel horizontal bands and/or flicker in
horizontal single-pixel bands) It could be complete coincidence, but the wi=
dth
of the corrupt band seems to be the difference in width vs. 3840x2160, i.e.
aobut 256 pixels. With this timing there are no messages in dmesg.

I've tried with a couple of "distro-friendly" bisect=
ion approaches so far but
run into problems both times, probably partly due to the relative age of the
kernels; I can try vanilla bisection but haven't looked into the details of
that yet.

Is there anything else I can do that might help identify the problem in the
interim, or is bisection the only option?
