It looks more like a binary blob to me, but I guess there are some tools to inspect it: https://cloud.xogium.me/s/wDf9bOWZU3cngw8/download (dirrect link). As for the dmesg output, the first logs I posted were exactly this, all kernel messages filtered from journald, and nothing serious seems to have changed. I will redo it as soon as I have a chance and post it. I cannot use dmesg because there are so much info generated the buffer is incomplete, hence the use of journalctl -b -k. Doesn't really help that the poor board is having a load average of 5 while doing this, but I will try to capture a new debug log.
