Hi Niklas, according to comment #4, yes a backport is needed - simple
cherry-pick wasn't possible.
Thx

Compiling the patched bionic kernel on bionic spits out less warnings,
but this error stays:
...

To manage
I was able to apply the patches, but only in the order:
1) apply 0001-s390-pci-Recover-handle-in-clp_set_pci_fn.patch (based on
17cdec960cf7)
2) cherry-pick 576c75e36c68
However, the test compile (on focal, but that shouldn't matter) failed:
make[2]: Leaving directory
'/home/ubuntu/bionic-lp187
This got fixed based on LP 1863768 for focal, and is with that also
fixed in groovy.
And it also landed in eoan via the stable release update processed in LP
1868324.
Hence only bionic is open.
