Hello all,
Please help me with root cause of [subj] error.
I have following setup:
1. kernel 3.4 (probably some fixes are absent).
2. Read/write ext4 partition mounted with:
nosuid,nodev,barrier=1,noauto_da_alloc
3. Partition located on eMMC device.
4. This is Android board.
Error occurs, while doing simple reboot loop:
1. echo u > /proc/sysrq-trigger
2. poll for all /proc/mount is read only
3. power cycle.
4. goto 1
kernel log:
