[help] JFFS2 CRC failed in kernel 2.6.35

[柏均 葉]

Hi all,
 
Sorry for my poor English first.
 
I develop the NAND controller driver on kernel 2.6.35 and use 
it to format NAND flash(512B page, Hynix H27US08561A) as JFFS2.

Under overnight test by the storage test item of BurnInTest tool,
it appeared the following info:

It's so weird~ 
Although the crc failed appears from jffs2 layer, the written file 
seems not to be corrupted.(The comparison is accuracy)
Is it the issue of driver-level? 
 
However, this driver has passed the test-modules under 
<linux source>/driver/mtd/tests and the storage 
test item(Sequential data pattern, random seeking,...etc) of 
BurnInTest tool for 69 hours when the flash is formatted as 
the UBIFS filesystem.
 
Refer to the posts before, the CRC failed usually occurred in the case 
of power off when the gc didn't complete. 
But, I don't cut the power when I run the BurnInTest tool for 
overnight test.
 
Any suggestion or question is welcome!!
I will appreciate for your reply.
