Yikes - running self-built kernels brings back a lot of memories ;)

Anyway, going this route (using the `config` from Ubuntu 5.1.x as a
base and accepting the defaults for `make oldconfig`):

git checkout v5.1-rc1
git bisect start
git bisect bad
git bisect good v5.0

... first try @ e266ca36da7de45b64b05698e98e04b578a88888 is a `git
bisect good`

Will report back, when I've got a result...
