Thank you for completing this on -rc2 and thereby giving us a preview
of the final results.

This one was in the candidate list of patches for 19.11.x, but it
didn't apply cleanly.
I've asked for a backport in my mail on 20th May - in this thread [1]
But in the meantime that was all done and -rc2 that you have tested contains

34cc55cce6b1 ("eal: fix race in control thread creation")
af68c1d699be ("eal: fix hang in control thread creation")

In the form of these backports:
$ git tag --contains 555da24882e1ca836f9532304f5f58034e57ff5e
v19.11.9-rc2
$ git tag --contains 0b8f4f0462f2260fc618e297e91317a891c6d255
v19.11.9-rc2

So if af68c1d699be really was meant to fix this known issue then it
does not do so in 19.11.x.
@Luc - I'm setting you to CC in case you happen to know why.

Ok, so hopefully this will eventually be fixed in 21.08 and then also
in the respective 19.11.x afterwards.

Known - currently we have to decide if we break SP3 (no change) or fix
SP3 but thereby break SP2 (that is what was in -rc2).
DIscussions and mail threads are ongoing, Ferruh and I tried to pull
in Suse people as well since it all started with a kernel change
backport.

Thanks for confirming, the coming -rc3 (still a while to give everone
a chance for more backports) will have those fixed.
If anyone needs it asap, it already is in the WIP branch on
