Yes, i can confirm that the Quartus 9.1SP1 solves this issue.
Also that Quartus 9.1SP1 can be installed over Quartus 9.1 with the patch mentioned in this thread.
Did you only upgrade the nios2eds from 9.1 to 9.1SP1 ??
You will have you upgrade the Quartus as well to 9.1SP1.

I am so sorry that I gave a wrong message before. I just install NII 9.1SP1, then I use Flash Programmer, it does not work ok with abnormal boot. When I download QII 9.1 SP1 completely, and install it. I recompilate the QII, now
both the Nios II IDE and the Nios II SBT, the EPCS works normally.
However, when I use Nios II SBT Flash Programmer, after enable the "Erase Flash Before Programming", the EPCS does not work normally again. The other options are OK, just watch out the "Erase Flash Before Programming" option.
Thanks everybody who helped and helping me.
Yours sincerely,
