Recently I had a Yaffs2 crash issue. It crashed in
yaffs_AddObjectToDirectory.
I ran stress test with a tool, fsstress, on Yaffs2.
The steps I used is listed below:
1. Run fsstress to test any file operations on Yaffs2.
2. Reset device suddenly.
3. Repeat step 1, and step2
After the test, I found a device eventually failed to reboot successfully,
since it crashed in yaffs_AddObjectToDirectory.
The dmesg log is listed at the bottom:
The issue is very similiar to the message posted in
http://wookware.org/lurker/message/20100616.085237.b6e6828b.ca.html
It looks like a reused objectID.
Do you have any idea about this issue?
