And it is inconsistent as 2 times works out of 5 time loop with 30 second delay.

Hi Jason,
The problem I am seeing as I am unable to send reset ipmi command to ME via IPMB on i2c bus. I tried to give 30 second delay after power off and setting in ME recovery mode. Once I do force poweroff then only I am able to send any command to ME. I don't know what is the relation of power to ME access on i2c bus.
Regards

I checked with the ME team and ME reset to move from recovery mode to
operational mode should work. You can file a ticket with Intel support
to help resolve the inconsistent behavior that you see when doing this.
In the meantime, I will look over your patch.
