Yes, full reinstall over a wiped hard disk.

That was exactly the problem I had. Current kernels 5.4.x both on
Testing and Sid produce constant GPU hangs on my Intel HD Graphics
530, The ones that outputs "i915: Resetting rcs0 for hang on rcs0"
(https://bugzilla.kernel.org/show_bug.cgi?id=205545). It is supposed
to be solved on 5.4.x but it is still present.

So... no current Debian kernel is bug free and works needs to be done.
This is the real problem.

Downgrades are not supported, did you re-install?

Try the kernel from backports, currently 5.4.
