Hello,
ty for the reply. I'm using the internal gfx of the Intel i3-8100. I have ECC unbuffered RAM, but I thing this shouldn't be an issue. How can I get these packages? I used the xen-hypervisor-common package from the debian buster repository. If I try to build it (debian too), I run into errors. Is there a docker build environment or something?

I'm pretty sure this one is taken care of in 4.11.3; it looks like your
gfx card has its frame buffer at an address which is a multiple pf 4Gb.
The later crash may then be a result of the earlier issue here. Please
retry with 4.11.3, and in case this still fails please also try with
4.13.0-rc5, if at all possible.
