FS#1877 - SD Card corruption on reboot after power failure
- problem occurs on zbt-we1326 with mt7621 cpu with mtk_sd kernel module loaded.
- openwrt latest snapshot(30-08-2017) firmware downloaded from openwrt.
- Steps to reproduce
1. setup extroot on the sdcard with a partition of 1gb(ext4)(boot) mounted as /overlay and 31gb(f2fs)(data) mounted at /media/
2. works fine on normal reboot(through ui).
3. turn off router power and start the router by plugging back in. notice corruption of extroot or data folder or both . it doesn’t happen rarely but it definitely happens on subsequent power off/on cycle.
