The test steps are: 1 mount /dev/mtdblock0 to /mnt, which is a nandsim partition 2 copy a small file(2755 bytes) to /mnt 3 umount /mnt 4 mount /dev/mtdblock0 again The CVS snapshot before 2005/11/13 is good; the snapshot after 2005/11/13 is broken. I checked in EBH patch on 2005/11/04, so this is not a bug in EBH. Anyway I'll take look at the diff between 2005/11/12 and 2005/11/13 to find the bug out. For snapshot before 2005/11/13, I also did some stress test on /mnt, it works very well. For snapshot after 2005/11/13, kernel panic can be easily reproduced by copying a small file. Thanks, Forrest
