You don't happen to have a verbose curtin install log where it times out (the failure path)?
The error on rescanning partitions is a side-effect from one or more of the bcache devices
from not getting shut down properly which keeps a hold on the underlying device which prevents
access to the device exclusively, hence the error; however the failure is before this.
Getting the verbose logging from curtin (like you did for this successful install) will help me understand where the bug occurred.
Thank you for the config and an install log.
