this message is a re-post of the FreeBSD forum. Moderator cpm suggested =
to ask for help in this mailing-list:
In May I started with 10.0-Release on an ASrock E3C224D4I-14S.
The system had low power consumption and powerd(8) did a good job =
lowering the CPU frequency.
However starting from 10.1 (and now 10.2-release) I keep getting high =
CPU consumption due to a process called {acpi task}.
BIOS upgrades or changes didn't help. Disabling ACPI results in system =
halt at startup.
Does anybody have an idea to solve this? It seems that the ACPI process =
in FreeBSD is changed, which my motherboard cannot handle.
