Spontaneous numlock

[ab1jx]

Hmm, this is an sd card, a new Sandisk I bought about January to do this with.  My last backup image of it is dated 3/23/2021.  I make them with dd onto my nvme drive when I think of it, but I only kept the last one.  My original eMMC with Stretch is still in place, thats what I boot to to make backups, but it crashes a little more often than the numlock problem.  This is happening every couple days at this point.  I could just turn numlock off except that doesn't work.  I can't turn it on or off from the keyboard. I don't know what most of those Fn+top row keys do normally, Insert is the only one I use. There's something missing in the way generic arm64 Debian got debootstrapped on here, they've never worked.
