Comment(by martin.langhoff):

 Interesting find.

 My SKU 294 1.2GHz unit that had been S/R rock solid under runin had a NiMH
 battery. Swap over to a discharged LiFePO4, and it repros the hang booting
 to linux, stopping powerd, running an rtcwake loop.

 In the last s/r before the hang, I did get strange mwifiex messages:
