after a little modification (which made a difference even though it shouldn't have), I have been able to get output from part_blk. Now, I have narrowed the problem down to the following bit of code:

                Sector(unsigned long blk_nr,
                       unsigned long count,
                       bool write = false)
                : _session(Driver::driver().session()),
                  _p(_session.dma_alloc_packet(Driver::driver().blk_size() * count),
                     write ? Packet_descriptor::WRITE : Packet_descriptor::READ,
                     blk_nr, count)


Somewhere in there, it freezes. If I had more time, I would break it up and dig deeper.

I stepped through your video log and could not find anything
suspicious beside the fact that part_blk does not print anything. Did
you you really add something like the following to
repos/os/src/server/part_blk/main.cc?

  int main()
  {
    using namespace Genode;

    PINF("I just started");

    if (!Block::Partition_table::table().avail()) {
      PERR("No valid partition table found");
      return 1;
    }

    PINF("Partition table parsed");

    ...
  }

Could you send me (or the list) your current version of the used run
script? I'll try to adapt it to Qemu with AHCI and investigate
further.
