Hi, modules built with gcc-11 14ubuntu1 toolchain have the gcc-11 stable ibmz PLT patch already reverted to make things work again.
One needs to downgrade gcc-11 to 13ubuntu1 to experience the breakage. You can fetch older gcc-11 from https://launchpad.net/ubuntu/+source/gcc-11/11.2.0-13ubuntu1/+build/22629238 and you will most likely also need older binutils from https://launchpad.net/ubuntu/+source/binutils/2.37-10ubuntu1/+build/22423687 You can pull those debs with: $ pull-lp-debs --arch s390x binutils jammy 2.37-10ubuntu1 $ pull-lp-debs --arch s390x gcc-11 jammy 11.2.0-13ubuntu1 And downgrade packages that you have already installed to versions one pulls down with the above commands (i.e. one does not need _all_ of the packages pulled).
