I originally thought that the AHCI driver wasn't working, but my issue may be with the part_blk driver. The part_blk driver never starts, but AHCI announces service "Block". Any help?

Maybe your config files is missing routing entries for the Block service? Please have a look at repos/os/run/part_blk.run or try
<config verbose="yes"> ... <start name="part_blk"> ... <route> ... <service name="Block"> <child name="ahci"/> </service> ... </route> ... </start> </config
Regards
The routing is good. part_blk works just fine if I use rom_blk to provide "Block", but if I use AHCI to provide the service, part_blk doesn't give me any output.

Please try to start debugging in part_blk/main.cc and the implementation of Partition_table. With more information, we may be able to help you - without we can't.
Happy coding
Thanks. I have sent a video and a photo from booting--serial debugging doesn't work with my new computer. The email is awaiting moderator approval. I will try what I can as far as debugging goes; I'm not sure how well I can do since the code is a little hard to follow at places--whoever wrote the code didn't document it much better than I would :(.

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.

Are you sure that part_blk was started by init? You can use the verbose="yes" attribute in your config file.

Yes, I put in printfs at every seemingly significant point. I used an almost identical rom_blk config for comparison, and it printed all the output it was supposed to. As for adapting it to Qemu, at least with my version, AHCI never announces service "Block". I'm using Genode on real hardware (an incredible fast computer I built earlier this month). The kernel I'm using is foc_x86_32. I've attached the config file, and the rom_blk version, since I'm not using a run script. As for the bootloader, I'm using grub2 with legacy_configfile. Note that I have verified that part_blk is on the list of modules loaded.

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.
