hwpstate0: set freq failed, err 6

[darkryoushii]

Hey,

I recently enabled powerd in FreeNAS 8.3.1 RC1 and started getting the following messages in console footer (trinity is my NAS name):

Code:

Feb 25 23:15:44 trinity kernel: hwpstate0: set freq failed, err 6
Feb 25 23:16:15 trinity last message repeated 9 times
Feb 25 23:17:42 trinity last message repeated 14 times

The server is running an AMD A6-5400K with the rest of the specifications in my signature.

I have found this patch http://lists.freebsd.org/pipermail/freebsd-stable/2012-May/067758.html though I have been unable to test it as I don't have the know-how to build it and implement it.

I really would hope that this can be fixed fairly quickly, as my power usage is 5x higher without it being able to idle at low frequencies.

Any help would be greatly appreciated,
DarkRyoushii

Was this present on a previous version of FreeNAS? It would help for continuity.

I have the same message with my A4-5300. It seems to affect all AMD CPUs with Turbo. Frequency scaling still works though.
Until the suggested patch makes it into the FreeBSD kernel I wanted to use a setting to avoid the spamming of my log: http://forums.freebsd.org/archive/index.php/t-11356.html
Unfortunately /boot/loader.conf is read only. How can I edit this file?

 

[PowerWiesel]

mount -uw /

The filesystem is read only so what that command does is allows you to modify this and edit the loader.conf file (otherwise you'll get an access denied). When finished modifying the file one can set the filesystem back to read only by typing:

mount -ur /

(if it still wants someone to know)


i tried

hint.acpi_throttle.0.disabled="1"

in /boot/loader.conf, but it does not seem to make a difference for me.

still freenas kernel: hwpstate0: set freq failed, err 6

AMD FX(tm)-4300 Quad-Core Processor (turbo disabled) on SABERTOOTH 990FX R2.0

Does anyone have an idea in the meanwhile ?

Yes, stop using AMD just like the post above yours says. ;)

Sorry but using AMD means you are in a small island with a small number of people. As such, you're almost on your own to solve the problems. :(

SOLVED?: I too was getting this exact error after upgrading to 9.2.x, this did not occur in 9.1.x or previous versions. Various Google searches did not help until I read Schwinni's comment about Turbo. I decided to Google Turbo. The gist was to disable Turbo mode and Cool n Quiet in the UEFI. I did just that and after reboot I have yet to have a single error after 30 minutes so far! I made a few other settings changes too which may be overkill but here's what I did:

• Overclock Mode
  • Manual - 100MHz
• AMD Turbo Core
  • Disabled
• Advanced > CPU Config
  • Cool n Quiet
    • Disabled
  • SVM(virtualization)
    • Disabled

fwiw: Yes, I know I have improper hardware running my home server. I didn't know better when I started. I do now, but I don't have $600 right now to buy a Xeon processor, Supermicro mobo and ECC RAM.

Here's my processor and motherboard for reference:
AMD A6-5400K Trinity 3.6GHz (3.8GHz Turbo) Socket FM2 65W Dual-Core
ASRock FM2A85X-ITX FM2 AMD A85X (Hudson D4)

For me, no. Everything was fine up until 9.2.1.3. (I can't seem to remember if it was present in 9.2.1.2 or 9.2.1.1 since these releases were so close.)

Do the following. Enable turbo and all power saving features in bios. That will do a better job than powerd. Then, disable powerd. Done. Solved. And it will save power as well. Without powerd. Cheers!
