Hi,
I've installed my rootfs on nand flash with ubifs, when trying to
syspend to disk (swap on sata HDD), the system hangs after saving the
image, after two minutes I got the message below, if I manually reset
the system, it succeeds to resume.
please note that the page offset is 0x80000000.

I guess it is related to the fact that the "ubi_bgt0d" thread is frozen,
and then the reboot notifier is called and this notifier tries to stop
the frozen thread.

Try to comment out thread stopping in the reboot notifier. It is not
needed anyway.

But I think I will remove this UBI reboot notifier, because it does not
solve any problem, and it seems it actually introduces new problems. See
this post:

http://lkml.org/lkml/2010/2/12/114

Thus, if you confirm that commenting out the stuff in the notifier
helps, I'll remove it.
