cannot boot latest RCN image from 2016-09-28 on BBGW

[Stephane Charette]

Trying to test the latest RCN image from 2016-09-28.  But I get a kernel panic before the flashing begins.  Serial debug console shows these errors:

Begin: Running /scripts/local-premount ... done.

Begin: Will now check root file system ... fsck from util-linux 2.25.2

fsck: error 2 (No such file or directory) while executing fsck.ext4 for /dev/mmcblk1p1

fsck exited with status code 8

done.

At this point everything hangs.  Anyone else seeing the same thing?  Build used is this one:  https://rcn-ee.com/rootfs/bb.org/testing/2016-09-28/seeed-iot/BBGW-blank-debian-8.6-seeed-iot-armhf-2016-09-28-4gb.img.xz

Nevermind.  I tried several images over the past 2 months, and they were all failing the same way.  I completely shut down my desktop, rebooted it, re-wrote the latest image to my uSD card, and now it is all working again.  Latest image is up and running on my BBGW.  Lost half my evening to this issue.  I don't know why/how Linux sometimes seems to lose its shit when writing images, and when it happens, a complete reboot seems to be the only thing to fix it.

Sorry for the false alarm.

Have you tried etcher.io instead of dd?

Just tried it.  Definitely more friendly than dd.  Thanks for the suggestion.
