[SOLVED] System load on idle is ~.30 after update

dudefellaguy · 2012-05-13 23:14:18

After doing an update my system load now hovers around ~.30 when idle. I have a pretty mininal system so this shouldn't be too hard to figure out. Before the update my system load would usually read 0.00 0.01 0.05 when It was idling. Now it seems to jump at random times.

Conditions which seem to produce a higher load are when:

MPD is playing a song, Having it run while stopped does nothing
A program is running that measures the system load such as htop or i3status
Firefox is running. It seems to effect the load more now (but I could be wrong on this one)

Even without X running, if I have htop or top running the system load spikes randomly. If I check it periodically with uptime the load stays at 0.

This is the pacman log from the time I last knew for sure that the load acted normal up until now:

I'm pretty sure things were normal after the 2012-05-12 13:27 (1st) update but I don't know for sure and I didn't want to leave anything out. I also believe the problem started after the 2012-05-12 13:27 (2nd) update but again, I didn't want to leave anything out.
Any ideas?

See this and this

Thank you! Mind I ask what you searched for to find those posts?

For anyone with a similar issue, the problem was caused by a kernel upgrade which happened just before the oldest update that I posted. To fix the issue I downgraded the kernel from 3.3.5-1 to 3.3.4-2

I don't know how skunktrader found it, I've had them already bookmarked (I'm subscribed to all Arch rss feeds) ;P

Sometimes it's not easy to find the right phrase to search for. 'load average' seems to do the trick.

But... it is ok to mark it SOLVED when the "solution" was to downgrade it, and it continue happening on later kernels (or whatever is causing it)?

dudefellaguy · 2012-06-07 21:16:37

This is a temporary solution to the problem, and one of the links that skunktrader is a a bug report. There is nothing more we can accomplist here.

I agree, it would be better to not mark this [Solved] until a real solution is found.

litemotiv, luuuciano: I agree that the "solution" is not a very good one, but, taking the stated problem and context of where it was posted into consideration I think that "[SOLVED]" is appropriate. My system load no longer idles at a high number (which was the originally stated problem in the subject field) and this subforum is particular to pacman upgrading issues, not to linux kernel issues. But if you really think that I should remove the tag, then I will, because, based on your post counts, you two obviously have more forum experience than I do.
