ACPI on or off?

Eugene

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

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.

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.
