The test suite from dqlite and cowsql sometimes fail to correctly build on Fedora for the ppc64le architecture. A rebuild of the packages would usually "fix" the issue. E.g.:

cluster/restart                                             
  num_records=0                                             [ OK    ] [ 0.07839130 / 0.00605561 CPU ]
  num_records=1                                             [ OK    ] [ 0.08852291 / 0.00816774 CPU ]

Also Incus/LXD seem to be affected by regular build issues on ppc64le. E.g.:
