NAND flash, Qualcomm platform, Linux kernel, Yaffs2, Android^^
Already find the root cause of this issue, and Qualcomm already fix it 4 month ago.
The root cause is about clearing the NAND error status.
(I am not sure I can share the detail or not)
Though Qualcomm already fix it, but 2 more suspicious points wanna check.
One of them is the mechanism of marking block as bad.
The other is the status checking mechanism.
