Nothing has been done about the multi-socket/multi-core PowerMac G5's and G4's ending up with processes stuck sleeping for long periods. The times used for sleeping and such on the various cores are still not sufficiently well matched across cores (other than accidentally for some boots). The fans are from pmac_thermal sleeping longer than it should, for example. bufdaemon and bufspacedaemon timeouts noticed at shutdown are from those being stuck-waiting as well. > I seem to recall something odd about the old PowerMac G5 units not > allowing multiple processor cores. There still are problems, more than just the sleeping too long issue. > Regardless I will get that test going now. >=20 =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
