Without this or something doing a similar deal, a Panda ES will blow chunks after a short period at 1.2GHz.Hi Andy,
I agree kernel panic is better than blowing up the board, but that might indicate the scaling is not working very well.
Also, does that mean I should not use the 12.02 image because the risk of blowing up my board?
No, "blowing chunks" (slang for vomiting) is different than "blowing up"... the 4460 has a separate comparator that is able to reset the SoC if it gets really too hot.
It will crash colourfully before then is what I mean, unless one of these thermal mechanisms is helping. It varies by chip actually, some can idle at 1.2GHz for a long time before choking others crash in a few seconds.
I can't really remember the status a year ago, we had it working a while before Panda ES was available IIRC. I did not hear of any actually burned 4460, I think the reset mechanism will save it. Tilt-3.3 and -3.4 should be fine at least.
