I think it was 3.6.y or 3.10.y

I suppose at least since 2012-10.08 [1] as this is the same Raspberry Pi
and, afair, the same fs. So it was 3.2.27 and then some of (some of them
was unstable) 3.{6,10,11}.y

It was almost idle except once a day or two accepting backup from
another machine (but that was kept on external drive/fs).

Could be, but compilation was made on external drive. nilfs holds the
rootfs and almost nothing more.
