I'm trying to create a custom Turmvilla-like scenario on my computer, but I'm running into a problem similar to the one Nobody III experienced (https://sourceforge.net/p/genode/mailman/genode-main/thread/20150601102048.GR9181%40genode-labs.com/#msg34161774) : when trying to access a physical hard disk with ahci_drv and part_blk, both components are launched, and ahci_drv reports the ATA device correctly, but the session is never built (part_blk hangs somewhere in the Driver constructor and ahci_drv never executes the _create_session function of Root_multiple_clients). The test run script works perfectly on Qemu however, and the content of the drive is read correctly. I experienced the same issue on my laptop, but I couldn't get any debug information because it doesn't have a serial port. Enabling or disabling IOMMU didn't affect the outcome.
