However, after the upgrade, the miner has stopped hashing twice, and the only way to recover is with a cold reset. Is this a know issue?

The cause is probably related to mains net pollution. This could be a high power device like an airco switching on and off on the same circuit on your fuse box. Perhaps the spike only presents itself once a while and that is why you did not notice until now. It does not look to be software related.

I don't know what "mains net pollution" is Huh

The power going into my unit is VERY clean and isolated from all other loads. (think data center)

I'm tempted to go back to a previous firmware because the extra 2GH/s benefit is lost when the unit stops hashing.
