Follow-ups

 

--- Graf Yang                                                2008-08-04 03:21:13

This bug have the same reason like [#4283], and had been fixed.

 

--- Graf Yang                                                2008-08-08 02:01:44

Vivi found this issue again, so set the resolution to none.

 

--- Graf Yang                                                2008-08-09 02:30:29

The bug found in this turn test can be duplicated on the first reboot when

flahed the jffs2 images.

 

--- Graf Yang                                                2008-08-09 21:45:53

Sorry, I draw back my previous submmit. In the first boot after flashed jffs2

images, there are some erase and flush work for the super block, it may take

more than 30 seconds. So the jffs2_test.exp will send reboot command after 1

minutes. I changed the wait time to be 5 seconds, so I can saw some reboot

problems, in fact, it's normal.

 

My self build image can reboot more than 380 times.

 

--- Graf Yang                                                2008-08-10 22:14:06

Vivi's images have failed test after reboot 127, 89, 14, 4.

My image ran 380 times, 400 times, and stopped by manually.

 

--- Graf Yang                                                2008-08-11 05:40:44

I built the lasted uclinux-dist use Vivi's toolchain, Vivi's kernel config, have

ran 2 turns, can't dup this issue.

 

--- Vivi Li                                                  2008-08-11 23:39:36

It can't be reproduced now. So close it.
