As far as the docs tell, bcache is designed to shut down unclean. So this is expected behavior in write-back mode. To cleanly detach a bcache, you would need to first put it in write-through or write-around mode and wait for write-back to finish. In turn, this mode should also avoid these messages at boot. -- Regards, Kai Replies to list-only preferred. -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
