This makes completely no sense.
In Your previous post You said that the connection was lost after a series of warnings saying that the critical temperature has been reached. Practically this means, that the CPU has nearly melted down (max Tjunction is 100deg.C, and the treshold is 95deg.C).
The kernel parameter
intel_idle.max_cstate=1 completely disables power saving - how could it help in this situation?
Yes, there was a problem with hard lookups in BayTrail CPUs, where this option was used as a workaround - but this not the case here.
I think that some other factors could have come into play here - like f.e. someone have "fixed" a problem with air conditioning system by opening all the doors and windows in that not-so-cold room
