Hi,
I need help.  I am wondering if anyone has experienced the same problem.
After mounting the JFFS2 on an empty NAND flash chip, a page fault
occurred.  The Linux kernel version is 2.4.6.  Here is the error log:

-------------------------------------------------------------------------------------------

[root at RedHat7 /root]# mount -t jffs2 /dev/mtdblock2 /mnt2
