ACPI on or off?
-
Sorry for the question with probably obvious answer but "does it make sense to run pfSense with ACPI on?"
-
In most cases, it's best to run with it on. Only turn it off if you have problems.

I am using HP DL360 G4 in CARP config.
Noticed weird issue on passive one:last pid: 53447; load averages: 0.28, 0.19, 0.11 up 60+19:06:31 13:41:15 105 processes: 5 running, 81 sleeping, 2 zombie, 17 waiting CPU: 0.0% user, 0.0% nice, 1.4% system, 38.0% interrupt, 60.5% idle Mem: 56M Active, 20M Inact, 67M Wired, 36K Cache, 46M Buf, 3365M Free Swap: 4096M Total, 4096M Free PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 11 root 1 171 ki31 0K 8K RUN 1 1388.3 99.07% idle: cpu1 26 root 1 -52 - 0K 8K CPU0 0 985.7H 87.60% irq9: acpi0 12 root 1 171 ki31 0K 8K RUN 0 462.5H 16.06% idle: cpu0 29 root 1 -68 - 0K 8K - 1 521:18 0.00% em2 taskq 28 root 1 -68 - 0K 8K - 0 363:45 0.00% em1 taskq 61093 root 1 8 20 9636K 8364K wait 1 295:01 0.00% sh
acpi consumes lots of resourced and I am not sure what causes it/how to kill it.

Tried a BIOS update?
Also, is anything sharing that IRQ with ACPI?
check the output of vmstat -i
I'm not sure if top and ps only report the first device on an IRQ or if it gets more specific.

I have to reboot server to check for version.

Most recent version of BIOS. Probably something is wrong with this particular box as I have number of clusters with the same type of hardware and everything is ok with them.
Anyway the answer to my question would be "ACPI should be on".
Thank you.
