Install of 10.2-RELEASE gives permanent CPU load
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.
