Qcpwrdn issue on WP7603

Hi,

Posted this on the mangOH forums, but also posting here as we haven’t received a reply and this issue is turning into a massive show stopper for us. If anyone can help us understand this problem that would be extremely helpful.

We’re seeing an issue on our mangOH Red units that shutdown for unexplained reasons. Here is a crash log we were able to extract.

Does anyone know what QCPWRDN means, and why it would cause a random shutdown?
