An update, not quite 1 year later. I encountered another segfault issue.

It began with my email report to the linux-btrfs mailing list titled
"BTRFS Balance Hard System Crash (Blinking LEDs)" just the other day.

Essentially, I had run "btrfs balance" on my btrfs filesystem
drive/partition (not sd-card).
It looks like it had completed or was just about to complete when I
came back to my computer to find my keyboard numlock and scrolllock
leds were blinking.
The short of it was that I thought something about the "balance"
process caused the problem.

Then I encountered boot issues, and then when I was in, I later
encountered issues which dealt with my f2fs (sd-card), where programs
weren't being run because of libutils (glibc).

So I was forced to do another reboot and everything seemed fine until
I went to sleep and woke up again to blinking leds.
No btrfs process/action was being taken.

I spun up my KDE Neon sd-card, which I'm in right now and running a
btrfs scrub on my btrfs drive as I write this.
I also ran an fsck.f2fs on my sd-card (not kde-neon), and it got bad
right away...

Mar 27 06:22:07 neon kernel: fsck.f2fs[6302]: segfault at 5564d32978f5
ip 000055651c124919 sp 00007ffd202ff9f8 error 4 in
fsck.f2fs[55651c121000+1c000]

This kde-neon kernel version is 5.4.0, and the associated tools
version is f2fs-tools-1.11.0.

There hasn't been any power-outage that I'm aware of.

With that segfault, I'm thinking that fs is now toast, and I need to
rebuild that arch-linux partition. At least /home was on btrfs which
is still accessible.

While I'm at it (scrubbing btrfs), I think I'll memtest my RAM and
badblocks my sd-card.
