You meant 93F right? Not 93Celsius (that's almost 200 degrees F)
First off, I would go back to your previous boot environment and check to see if the problem
resolves itself. if it does, it's going to be either a BSD compatibility issue with the mobo chipset,
or a bios update. From time to time BSD drops support for hardware and your board/chip/bios
may be affected.
I mean 93C assuming sysctl reports it correctly?
I just changed one thing that I can't imagine was the root cause but who knows — I rebuilt a binary for the RealTek driver against the FreeBSD 11 kernel sources in a VM. If I don't use the RealTek-provided driver the network stack freezes after some condition related to utilization and requires a reboot, and after upgrading to FreeNAS 11 I knew I'd be needing to rebuild it.
After I built it, copied it over, loaded it successfully and the cpu throttle_log had either hit 1 or stayed at 0 across all cores, the problem resolved.
I suppose it's possible that attempting to load the old module unsuccessfully could have put the kernel into a state where it was absurdly busy or something that resolved itself after loading a module that worked?
Or could be completely unrelated.
I'll include the relevant/interesting values from sysctl in-line:

It's holding in the 50-60Cs now and as long as that continues to happen I have no problem. Would really like to know the root cause though obviously so that it doesn't melt itself while I'm out of town.
