ACPI on or off?

[Eugene]

Sorry for the question with probably obvious answer but "does it make sense to run pfSense with ACPI on?"

[jimp]

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

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.

[Eugene]

I have to reboot server to check for version.

pkg_add -r dmidecode

dmidecode

That will get you the BIOS info you want.

Looks like it's on its own IRQ, so it must be something there… not sure what, though. If a BIOS update doesn't help, it may be best to shut ACPI off in the BIOS or in the OS.

[Eugene]

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.
