Regular readers will know that the M8 uses a Blackfin Digital Signal Processor made by US company, Analog Devices, Type ADSP-BF561.

To give you an idea of what it's like working with this beast, here is a list of the 97 bugs which have been found in the chip, "Silicon Anomalies" as they like to call them and the recommended workarounds. The chip revision level on the camera I dismantled is 0.3. so the entire list of bugs on pages 2 - 4 of this document applies to the processor used in early M8s. There's a cleaner version of the chip, revision level 0.5 but even it has some unresolved bugs.

They euphemistically refer to "Infinite Stalls" which to you and me are battery out lock-ups.
