Somebody in the thread at some point said:

| Everything boots and works properly while powered on. All my distros
| I've used work properly. The problem is when I shut down the device, it
| starts clicking, until I press power button again which then it does not
| click and appears in powered off state. Although, it still seems it is
| discharging as if it is on.

It sounds a lot like the A5 VB_SYS problem, the clicking noise is
actually coming from the ceramic capacitors that flex piezoelectrically
at the high currents during startup if that's the case.

Is it a fast tick-tick-tick type noise, like 10Hz, not apparently coming
from any particular place?
