Further Comments/Problems: The update went fine without errors. But booting with the new kernel did not work. The display went black shortly after loading the new kernel. I think it was the moment when it normally changes the display resolution. The boot process did not continue. Keyboard and mouse were not functioning. I had to hard switch off the computer. There were no logs written to disk. Fortunately my old kernel linux-image-4.19.0-18-amd64 was still able to boot. I solved the problem by inserting a boot parameter "intel_iommu=off" to grub. With this parameter the kernel from bullseye linux-image-5.10.0-9-amd64 was able to boot properly and the graphic was fine on console and with x. The kernel from buster did not need this boot parameter. I think the problem is, that the i915 gpu driver has difficulties to initialise my old intel graphic chip. According to lspci it is:
Which package has the driver you're using? I propose we reassign this package to that package for further investigation.
