I have been using the last EMLID OS image (called emlid-raspbian-20160718.img) on my RPi2 & 3 with the same result : the booting sequence is infinitely running on a sequence like the following:
maybe you can try another sdcard (maybe not compatible or faulty)
i had a more or less similar message a few weeks ago with a faulty sd-card (after 3 years of running fine 24/7)
Thanks guys for the advices
It indeed was coming from the SD card (even though it was a brand new one…)
Working well after full format but again same issue after expanding the file system in raspi config
No pb after complete change of the card
