I've tried multiple versions of gcc and here's the result:
- gcc 11.2.0-13ubuntu1 : bad - gcc 11.2.0-12ubuntu1 : bad - gcc 11.2.0-10ubuntu1 : bad - gcc 11.2.0-7ubuntu2 : good - gcc 10.3.0-13ubuntu1 : good
Apparently the last version of gcc that seems to work with zfs + kernel 5.15 is 11.2.0-7ubuntu2 (the one currently in impish).
The same behavior happens both with a vanilla 5.15 and our Ubuntu kernel 5.15 (only on s390x, all the other architectures are working just fine).
