Public bug reported:

Issue found with:
  * Jammy 5.15.0-102.112 
  * Jammy 6.5.0-27.28~22.04.1
On openstack s390x instance. Note that we didn't run ubuntu_ltp_syscalls on manually provisioned s390x instances.

This can be reproduced with Jammy 5.15.0-100-generic. But Mantic
6.5.0-27.28 is OK.

After some investigation, it seems that this might be a test case issue with recent LTP fork update.
