Thank you Greg, and thank you Alan for your explanations.

ok, so hope I have understood correctly and started a new bisect from

git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

, built it, tested it (5.2.0-rc3+) and marked as "bad",

and I hope have understood correctly and did

wget https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/snapshot/linux-4.20.tar.gz

and built it and tested it,

> Test that.  If it is "good", then great!

...and ok is good :-), so issued

git bisect good v4.20

...and I am going on there. So far:

$ git bisect log
git bisect start
# good: [8fe28cb58bcb235034b64cbbb7550a8a43fd88be] Linux 4.20

git bisect bad fcf010449ebe1db0cb68b2c6410972a782f2bd14

Please correct if I am missing something, or doing something different
from what you meant.

Thank you!
