Comment 2 for bug 1995941

Hello Nico, thanks for raising this.

The fix/patch c3f0e5fd2d33 "KVM: s390: pv: don't present the ecall interrupt twice" got upstream accepted with kernel v6.0, so I assume that it not only needs to be applied to 20.04/5.4, but also to 22.04/5.15 and 22.10/5.19.
And I've noticed that it got nice and properly tagged for upstream stable:
Cc: <email address hidden> # 5.7
Fixes: da24a0cc58ed ("KVM: s390: protvirt: Instruction emulation")

And with that it got already picked up and is included in:
22.04 with Ubuntu-5.15.0-53.59 (currently in jammy-proposed)
22.10 with Ubuntu-5.19.0-16.16 means already incl. in the release kernel.

So the only Ubuntu release that is affected is 20.04/focal, so I've set that as affected target series...
