Cat65k boot problem: Waiting for supervisor to come online in other slot

[grischast]

Dear all

I am facing this problem for the first time and the internet does not provide too much help about this one:

Here is a 6509 with Sup720-3BXL/MSFC3. It begins to load its image but then sits in an endless loop of

...

Waiting (slot 5) for supervisor to come online in other slot.  iteration = 31

Next Retry will be done after 6 seconds

...

All I can find on the web here is a hint regarding the modular software image (...-mz...) which cannot be used. But I have never used other ones than these mz-ones.

I tried to boot different images from the rommon but the result is always the same.

I guess there is some simple solution for this.... but what is it?

Regards,

Grischa

Additional note: The system booted normally before the rommon-upgrade to 8.5.4.

Have you solved that?

Thank you,
