N-4000 error: ENTRY_IO on iodc call

[Mugur Stef_1]

Does anybody know what the following error means:
"ERROR: ENTRY_IO on iodc call, status=+4294967291"?
I read this on a N-4000 with 2x550MHz processors.
Any key I pressed the message appeared again and I got rid of this only by doing a reset (from the GSP).
Have anybody met the following message (from the logtool, chassis log):
"processor system warning EE00"?
It's on the same system described earlier.

Verify with STM and see activity of processors with top.

This is a known problem that affects the N, L and A series systems. This problem can also be
duplicated by pressing the "break" key in the BCH main menu during a boot attempt.
If this replicates your problem then you need to havet he PDC revision verified on your N-class.

There is a relatively new PDC and GSP update that supports OLAR for 11i, this may be the right time to take advantage!

Good Luck,
Bill

Check if you have the lates PDC version, i think it is 41.02 for N class. You can chec that with STM, run mstm--> select processor->Menu->tools->information->run

I updated the PDC firmware to 41.02, I tried pressing the Break key and the error didn't appear so the problem is solved.
Thank you for the tips.
Does anybody know something about the second problem:
"processor system warning EE00".
This was what I saw when I ran logtool (from STM) and checked for chassis logs.
