Kernel oops after big-ish writes
#1
I've been trying to set up a rockpro64 for the purposes of a home server for backups; I have flashed the SPI so as to be able to boot off a USB. I had a Debian official installation on an SD with encrypted root going back in December when I noticed that any write operations larger than a few MB would give me a kernel oops (using tools like scp and rsync), and when I left it up for the holidays for a couple weeks, the machine crashed on its own. This problem seems to be independent of which OS I use; I've been trying to switch to Manjaro by flashing a USB stick and then rsyncing the contents of the root partition to a luks volume on an sd card, and I get a similar oops.

It seemed very similar to the problem described in this thread, but the solution offered here (compiling my own device tree blobs with trusted firmware) didn't yield any different behavior; although the thread leads me to suspect that it may have something to do with my having flashed the SPI partition, and there's firmware from when the rockpro64 booted off SPI still running that the kernel bumps into? However, I've used ayufan's as well as sigmaris' latest releases (sigmaris seems to be using atf for the dtb), and I continue to get kernel crashes.

What follows are the kernel messages from the most recent crash. I'm fairly new to dealing with things like this, so please let me know if I'm missing information that would be helpful.

Code:
#### lots of rsync to sd happening before this, when suddenly... ####
