Jo Røislien is a Norwegian mathematician and science communicator.
Or, at least, so says his IMDB biography.

Bacon: 3
As suggested by Oracle of Bacon:
Jo Røislien was in Chasing the World's Largest Number (2012) with Ronald Graham (I)
Ronald Graham (I) was in Director's Cut (2016) with Dave Johnson (XXVII)
Dave Johnson (XXVII) was in Frost/Nixon (2008) with Kevin Bacon
(The Wikipedia article mentioned above proposes a different path, through a TV show appearance with Ylvis; it's a 3 either way.)
Sabbath: 6
This was the trickiest part - I had to check many sources in Norwegian, and even one in Russian!
I think I've got it, though...
Jo Røislien was in Tøyen Airport with Ingrid Tolstad
Ingrid Tolstad was in "Zeppoliner" (Memoirs, The Third and the Mortal) with Kirsti Huke
Kirsti Huke was in Sidewalk Comedy with Eirik Hegdal
Eirik Hegdal was in Triads and More with Joshua Redman
Joshua Redman was in The Louisiana Gator Boys with Jeff Baxter
Jeff Baxter was in Four On The Floor (1979) with Glenn Hughes, briefly of Black Sabbath
Last two connections are courtesy of BandToBand.com, and cross-checked elsewhere,
I could have finished this with Joshua Redman - B.B. King - Ozzy Osbourne, but I couldn't resist a chance to improve the Sabbath number of Jeff Baxter.
Fun fact: I only found out about his existence because his Wikipedia entry showed up in a search for Erdős-Bacon-Sabbath numbers - specifically, it linked to one of the early EBS articles (apparently as a source for the existence of the Erdős-Bacon number).
...To be precise, the link went to a 2016 blog post by Len Fisher that tried to establish his own EBS number. I'm actually not sure why we still don't have Len Fisher.
