In detail: -without patch, powerd(8) and system working stable (20+ daemons), -with patch applied and disabling powerd(8), system working stable (a couple of hours) -with patch applied and trying to enable powerd(8) produces kernel panic from powerd(8) process. It seems something ugly using scheduling lives in powerd(8). info: ===== Copyright (c) 1992-2007 The FreeBSD Project.
