[flashrom] WG: SB600, shutting down IMC failed

first I have to clarify who built the firmware.

I'm not really involved in the development of the system. I'm just responsible for the test design of the system. 

I increased the mbox_wait_ack to 10 seconds but there are still the same errors. Do you know another
way to disable the IMC?

Then I'm very curious about Rudolf's ideas.

Best regards

Who build it and can you talk to them?

Oh, I was talking about the expectation you have about the state of the IMC assuming that you are somewhat involved in the development of the system (aren't you?). The IMC does not need to be active for a working system (AFAIK), but to me it seems like it is active but somewhat misconfigured. Let's see what Rudolf says about it. He know it way better than me.

In my version of the patch you need to increase the initial value of 'i'
in mbox_wait_ack. Similar in Rudolf's version, but it counts up instead.
The value is in milliseconds.
