As Peter said
$ xrandr -q
will show all modes detected and the current configuration. Then use the
normal xrandr commands to select your desired resolution. Also can you
attach full dmesg with drm.debug=0xe again, the one you've attached is
missing a few things at the top. Maybe your kernel dmesg buffer is too
small. You can adjust that size with log_buf_len=2M or so on the kernel
cmdline.

This looks like overscan/scaling-comp gone wrong (but I haven't ever seen
that in practice, so not much clue). Rodrigo is working on patches to add
support for overscan comp, maybe he has a few patches for you to try.
