we were using JFFS2 on kernel 2.6.11 and and JFFS2 root fs corrupts rarely. ST NAND flash: 128MiB with 2KiB page size, erase block size: 128KiB is used. U-Boot version: 1.1.6

I dumped corrupted jfss2 partition and found out that 3 blocks are filled with FF. I can boot the system via nfs and then mount this partition and list the files on it.However, when I give this root fs to the kernel, it does not boot.

we observed that this problem occurs when the linux hangs up and the the device is reset. most of the time it boots but in very rare cases,due to the root fs corruption, it does not boot.

if I erase whole partition and re-write jffs2 root fs again then the device boots.

any comments?

regards.
