Hi all,
I just patched the whole latest code from git server, and found some
problems after stress test.
The latest patch I used was "yaffs Update README-linux to reflect kernel
patching changes" (commit ed8b893aade8e0819a17bfa6009a6fb367ebb9c8) on
Sep 29, 2010.

)
What I did was listed below:
1. Got the whole latest code from git server.
2. Modified /fs/Makefile, and /fs/Kconfig, remove the original yaffs2, then
ran patch-ker.sh c m /Android2-2/kernel/ to patch the while latest yaffs2.
3. Ran stress test with a stress testing program, fsstress, on my device.
a. Ran fsstress, which folked 3 childs to run fsstress
b. At random time, we reset our device.
c. Repeated the above 2 steps.
4. I ran it for a nigth, and found it failed to mount mtdblock6 as /data
partition successfully in the morning.
The error message what I got was listed below. It seems that the data was
corrupted due to the stress testing, so yaffs2 failed to recognize it.
The device is in my hand now, The device is at my hand now, I could add more
debug to it,
Does anyone have any suggestion? Any comment are welcome! Thanks!
