p.s. Here's the current dmesg output: https://pastebin.com/nk92PYWe

So that's build #0613 with kernel 4.11.4.

Given the lack of any other problem reports of a similar nature while using this kernel (average 200 RPi2 daily downloads, since #0607) I'd say it's more likely to be something specific to your hardware/environment (SD card, power supply, power cable etc.).

If it continues after a clean installation then post again.

It might be useful to leave "bcmstat.sh y" running in an ssh window as this will record any under-voltage events - a "U" in the "UFT" column means an under-voltage event is currently taking place, a "u" means an under-voltage event has taken place (since the start of the script), and ctrl-c (to end the script) will show the total number of under-voltage events since the script started running.

Thanks for the instructions! I'll do further tests and will report back when I have more info.

Cheers,
anthonws.
