New test with the EVM and official Pandora 5V adapter, the red warning LED shows up on the board.
I am not sure if it is intended to be a "warning" LED... (Table 1 of the EVM description calls it "Red Power Input Voltage Indicator").
It shows up only with 5V plugged in, not with 12V.
I boot with the pre-compiled Letux-4.9.0-rc5 on Slackware -current armhf.
3 neon loops, 1 memtester on 2G. No problem after more than 30 hours, dmesg is clean. cpufreq stats: 1000 MHz:0.15%, 1.50 GHz:99.85% 64°C
Interesting! That seems to be fine!
Do I let it run ?
Can you also check the VSYS_COBRA voltage of your setup? It might be higher than mine @5V. It should by theory be 3.7V but in practice I have seen it to go down to 3.088V.
Here is a script:
http://git.goldelico.com/?p=gta04-kernel.git;a=blob_plain;f=Letux/root/tempe...
which locates the gpadc inside the PALMAS and reads the VSYS voltage.
Here it is : Wed Nov 23 09:13:24 -00 2016 64° 47° 51° 3449mV 1500MHz
And still running fine : $ uptime 09:17:06 up 1 day, 18:06, 1 user, load average: 4.38, 4.40, 4.37
