Comment(by Luna):

 use the "nandtest" the tool do three times of the test.
 I think you want me do the test for the front words. Is it right?
 The attached files are result from the test.

 Dear David,

 Could you tell me why the problem is nand flash problem after via those
 test?

 I stall have one OX, C-1-07-M1<SHF73300012>, has the same problem can not
 boot into systemt after do long run test.

 Now, the machine does not do any test after it happened the event.

 If it is really Nand problem, I want to swap the nand chip to test and
 verify.
 But I need to know your idea. Cause the even is not easy to dub.
 We had failed on 27 C-test machines and the same test way to reproduce.
 And the only one B4 machine, having same problem, flash image and do the
 test is also fail to reproduce.

 If it is nand problem, I need to find a function which can detect it and
 issue the message on manufactory test flow.
