System does wake up from hibernation, but there are errors in dmesg and system
is unresponsive.

Errors are:

Full dmesg is attached.

I have `amd_iommu=off` because I'm not able to boot otherwise (see

If more information are needed, I would be happy to provide them.

I've looked at next branch in git (drm-next-4.19) and there seem to be some
commits that could be relevant:
https://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-4.19&qt=grep&q=KCQ ,
however I'm not that good with kernel code so I have no idea if I should try to
use any of those commits :)
