OK, so with a 3G/1G user/kernel memory split, it becomes too tight. I
recompiled the kernel with a 2G/2G memory split instead, and then it works.
Not mounted:
# free
total used free shared buff/cache available

# df --block-size=G /home

That comes out to 108.515 kiB/GiB, or 108.515 MiB/TiB, confirming your
estimate above.
