JFFS2 peoblems with K3 strata flash on Dalhart

[Yuan, Cain]

Hi all,
	I am now test JFFS2 file system on Dalhart with Redboot as
boorloader, Linux version 2.4.18-rmk6-pxa2 and some patches for dalhart.

	When I first burned JFFS2 and linux image into k3 flash and load &
run linux it will report some  warnings but can boot successful.
later  I can   create/del files  on JFFS2 filesystem.  But when I reset the
board,   load linux na drun again, it will report  thousands of warnings.
after linux bootup,  create/del file will all  fail.   Here is the msg:
