You will then lose data. If you care about not losing data, then you have to wait for all of the data to be written out to flash. There's no magic pixie dust here. You can have a clean shutdown that might take a little while, and no data loss, or you can live with the potential risk of data loss if you can't stand waiting even a tiny bit of time for the shutdown to finish up. The other question is why is some user process writing so much to the file system before the system is shutdown. Is this really some ill-behaved user application which is burning huge amounts of flash lifespan and battery life by constantly writing to flash? Or is there some other bug going on which is causing system processes to write huge amounts of logs or other junk to the file system unnecessarily? -- You are receiving this mail because: You are watching the assignee of the bug.
