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. top -SH output: ---- last pid: 41184; load averages: 1.71, 1.75, 1.64 = up 8+14:05:40 10:00:16 691 processes: 7 running, 663 sleeping, 21 waiting CPU: 0.8% user, 0.0% nice, 62.7% system, 0.0% interrupt, 36.5% idle Mem: 90M Active, 4310M Inact, 11G Wired, 18M Cache, 144K Buf, 497M Free ARC: 9991M Total, 1364M MFU, 7997M MRU, 4841K Anon, 36M Header, 588M = Other Swap: 2048M Total, 2048M Free PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU = COMMAND 11 root 155 ki31 0K 32K RUN 1 122.7H 62.99% = idle{idle: cpu1} 0 root 8 0 0K 7088K RUN 1 73.2H 36.87% = kernel{acpi_task_1} 0 root 8 0 0K 7088K RUN 0 73.3H 36.18% = kernel{acpi_task_0} 0 root 8 0 0K 7088K RUN 0 73.2H 35.60% = kernel{acpi_task_2} 11 root 155 ki31 0K 32K RUN 0 67.6H 34.08% = idle{idle: cpu0} 1024 mysql 20 0 266M 69624K RUN 1 0:37 0.10% = mysqld{mysqld} 12 root -60 - 0K 336K WAIT 0 11:18 0.00% = intr{swi4: clock} 1149 root 20 0 500M 90016K sbwait 0 6:15 0.00% = mongod{mongod} 1149 root 20 0 500M 90016K sbwait 1 6:13 0.00% = mongod{mongod} 1149 root 20 0 500M 90016K sbwait 0 6:12 0.00% = mongod{mongod} 687 root 20 0 4560M 363M uwait 1 5:31 0.00% = java{java} ---- Regards, Arthur=
