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.

It appears that main() never actually starts with AHCI.
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.
