CPU problem ? (solved)

Hi,

for a few days, I've been noticing a little problem. My log files are quite big (kernel.log, messages.log, etc). So I looked into them and I fund they are completely flooded with this message:

What does that mean ? I can't even find what the problem is.

Sincerely

Re: CPU problem ? (solved)

Hi,

Are these related to your problem? https://bbs.archlinux.org/viewtopic.php?pid=1371296  - https://bugs.archlinux.org/task/37085 - if so please try downgrading your intel video driver to the previous version.

Re: CPU problem ? (solved)

I don't really know if they are related, I'm going to try to downgrade my video driver. I have a intel HD 3000, so the driver should be xf86-video-intel, right ?
But they published the last version on Feb 10th, and I started to face problem on Mar 8th. Is it really relevant ?

Re: CPU problem ? (solved)

Just a little up, I stil have the problem and don't know what to do to solve it. The log message is written every second and dangerously fills my log files.

About your issue at hand, I have no insight, sorry.  But the log files should be automatically rotated by logrotate from time to time, so I don't know just how fast they are filling, but they should be taken care by the logrotate.timer.

But if you want better handling of quickly filling logs, you should probably just use the systemd journal.  It rotates itself when it gets to whatever size you specify in /etc/systemd/journald.conf.  That config also allows you to specify the total space that the journal is allowed to use.

Sorry I can't help you with the backtraces.  I don't actually know how to read those things.

I have a very similar problem (on a Lenovo Edge E520 laptop, also with the i915). My log messages look like this:

Perhaps we should submit a bug report somewhere.

Re: CPU problem ? (solved)

Okay, I think I have the solution. Thanks to the french forum. I had the service powerdown, and one of its settings was responsible:

for i in /sys/kernel/debug/dri/*/i915_max_freq; do opt "$i" 350; done

This line could be responsible. I simply remove the service, as I don't need it.
