Hi Olivier, yes, this is supposed to be included in linux-generic 5.15.0-72: $ git log --oneline --grep "s390/unwind: fix fgraph return address recovery" cf3cb801c96a s390/unwind: fix fgraph return address recovery $ git tag --contains cf3cb801c96a Ubuntu-5.15.0-72.79 Ubuntu-5.15.0-74.81 (ignore the right most digit) But 5.15.0.72 is still in "-proposed": $ rmadison --arch=s390x --suite=jammy,jammy-updates,jammy-proposed linux-generic linux-generic | 5.15.0.25.27 | jammy | s390x linux-generic | 5.15.0.71.69 | jammy-updates | s390x linux-generic | 5.15.0.72.70 | jammy-proposed | s390x <== So you need to enable jammy-proposed to install and use it.
