** Description changed: + [Impact] + Certain kernel modules are unloadable (libceph & scsi_debug) due to the compiler generating unsupported relocations. + + This symptom is similar to LP: #1533009 but, in that case it impacted + all modules, and the fix for that appears to remain in place. + + [Test Case] + With the hwe-z kernel: ubuntu@grotian:~$ sudo modprobe libceph modprobe: ERROR: could not insert 'libceph': Exec format error ubuntu@grotian:~$ dmesg [66988.470307] module libceph: unsupported RELA relocation: 275 - This symptom is similar to LP: #1533009 but, in that case it impacted - all modules, and the fix for that appears to remain in place. + [Regression Risk] + The scope of the fix is restricted to aarch64, so regressions should only impact the arm64 port of Ubuntu. Regressions could impact when literal loads are used - which may have performance impacts or possibly cause software to fail to build/run where it previously did. This is somewhat mitigated by the fact that this has been fixed in artful gcc-5/gcc-6 and used on our buildds for some time. Only "somewhat", because gcc-7 is now the default.
