Who said that?
You mentioned on the mailing list that the SoC gets quite hot while it's frozen, so it's almost certainly in a tight loop going round and round and doing nothing while stopping the SoC powering down at all. I don't think it's getting stuck in a low power mode, or receiving a dodgy clock that's stopped the pipelines triggering or anything like that, but it could still be preparing to powersave when it hits this loop.Well, unfortunately, it improved the situation but it didn't fix it.
This probably also is the reason why the full apt-get upgrade for Nikolaus worked. As long as the Pyra is not idling, it doesn't freeze.
So it could be related to some powersaving that's triggering (with such system, powersaving already triggers when there's only 1ms of idling happening).

Times like this show how fantastic the community is here.
Once I called my ISP because my Internet connection was down. They asked me to reboot my computer. I politely informed them that none of my computers were turned on. They advised me to please power on a computer, so that I could reboot it.Have you tried plugging it out/in again?
... impissible ... (35c3).
That's sad, but it doesn't make your planned test (loading drivers, trying for 15 minutes) useless. You could still fence in one issue wit that method and reduce the problem's overall complexity.Well, unfortunately, it improved the situation but it didn't fix it.
After 3:10 hours, it froze again.
How do power state changes work, anyway? Does the software issue a special instruction or write some specific value to a particular register and the SoC does the rest? Or does the software have to handle some management around it, too?
