Hi, I’ve upgraded rest of my servers to Buster. There were BIOS and UEFI machines. But all were booted without any problems So this issue is related only to one machine. Unfortunately I have only limited VNC access to this server. I can see only this text:
Loading Linux 4.19.0-5-amd64 … Loading initial ramdisk ... And then nothing. Server stop responding even to ctrl+alt+del through VNC viewer. > Maybe you can give a try to the packages from stretch in order to make > sure it's grub2 the culprit of the issues you are seeing? Do you mean install grub2 packages from stretch to buster ? I will try and send the result.

Just to be transparent here, not all possible functionality is tested by the package maintainers (currently Ian and me) before throwing a new package into Debian. This is simply not practically feasible for us. [0] We rely on the upstream tests to know that the upstream Xen code will probably work. For Debian specific things, we do test our own use cases, but e.g. UEFI is not one of them. For this, we rely on active users to report problems and help solving them. So, yes, things like this can happen. Thanks for reporting this. Next step would be to follow Rogers instructions, and provide config dumps, serial console output etc... We're certainly available to include changes / etc to fix things, given proper information / testing reports from the user. But, the user has to actively help to make that happen.
