The ahci_drv has no matching policy and because of a bug in its policy
handling code (fixed on the current staging branch) aborts.

Your problem, however, is the missing policy for part_blk, e.g.:

        <policy label="part_blk" device="0"/>

in the ahci_drv config. With the policy in place, part_blk should
get access to the block device and your l4android component in return
should get access to the partition.


Regards,
Josef
